Hungry Anyone?

Don’t drive up to your favorite fast-food joint and ask for a Sound Burger. They won’t know what you’re talking about. But chances are, people into vinyl records will. Audio-Technica first released the Sound Burger late last year. It sold out within 2 days and until recently, had been on constant back order. So, what is this thing that had people waiting months to get? The Sound Burger is a new, belt-driven, portable Bluetooth turntable inspired by the original model introduced by AT some 40 years ago. It’s practically become the hottest thing in audio since the phonograph was invented. Nipper now has something cool to listen to when he goes outside to do his business.

Hurry Up & Wait

I was able to score my Sound Burger through a contact at AT, but still had to wait a few weeks to get it. Burgers are just now starting to show in stock on AT’s website, Amazon, and other places (links provided at the end of my article). I already own 3 turntables, so why get another one? My turntables are heavy, full size, and I don’t have room for them since I was forced to sell my home, so they’re packed up in boxes. I wanted a turntable that was easy to move, wouldn’t take up a lot of real estate, wouldn’t take up an afternoon to setup, and wouldn’t cost a lot. Those cheesy Crosley “suitcase” record players with their ceramic cartridges weren’t even a consideration.

Strange Looks

A portable turntable is a rather odd device when you stop to think about it. Are people really going to lug a box of records around and then plop down in a park, or wherever, and start listening while passersby gawk? It would come in handy if you frequented used record stores or flea markets and wanted to preview albums before you bought them. It would also be a very cool thing for a dorm room, provided no one steals your Burger. In my case, my Sound Burger is staying safely in my house. Besides, I get enough strange looks as it is when I go out in public.

Preparing Your Burger

Setting up the Sound Burger is as easy as deciding what condiments to put on a burger. The first order of business is to unscrew the locking pin on the back. Don’t forget to do this or you’ll damage the tone arm. Disappointingly, there’s no place to store it so be sure not to lose it. The next thing to do is plug in the included USB-C cable and start charging the Li-Ion battery. Now comes the fun part. Lift the lid, lift the tone arm, remove the rubberized clamp, place a record on the platter, apply the clamp (which cleverly doubles as a 45 RPM adapter), close the lid, turn the unit on, select 33 1/3 or 45 speed (sorry, no 78 RPM), and place the tone arm on the record to start the platter spinning. Your Burger is now well done.

Well, not quite. You need to connect it to something for the sound part of the Sound Burger to work. You have 3 options: There’s a stereo 3.5 mm headphone output, 3.5 mm stereo line output (audio cable included), and Bluetooth 5.2. There’s no volume control so if you’re connecting to something that has no volume control then you’re at the mercy of Sound Burger’s fixed level output.

Bite Me

Neither of my headphones have a volume control. Photo by Peter Skiera.

That output, as I discovered, is quite low, to the point where I wasn’t able to enjoy my cherished closed back Oppo PM-3 Planar Magnetic headphones. I switched to my Tin HiFi T4 wired ear buds but the sound level was even lower with those. Unfortunately, neither of those models have a volume control. Why AT failed to include a volume control on the Sound Burger is a mystery. A simple rotary volume control couldn’t have been beyond the realm of human engineering and couldn’t have been that costly.

Public Speaker

This isn’t what it looks like. Photo by Peter Skiera.

Above the Burger’s Power and Speed buttons is a simulated vented area that one might understandably mistake for a speaker grille. To be clear, the Sound Burger doesn’t have a built-in speaker. You must connect it to something to be able to hear it. This might strike you as odd that a portable audio device lacks a speaker, but I’m actually glad AT didn’t include a speaker. It would’ve added to the cost, would’ve been mono, would’ve sounded horrible, and would’ve had no volume control. Hands up anyone who wants to pay more for a useless feature.

Sound Burger’s Sound

Putting the unfortunate headphone experience behind me, I next connected my Sound Burger via Bluetooth to my portable Muzen Cyber Shell portable Bluetooth speaker. It paired and connected almost immediately and sounded excellent (thankfully, the Cyber Shell has a volume control). I have read of instances where the Sound Burger’s Bluetooth refuses to play nice with certain Bluetooth speakers and ear buds so you might want to have a plan b from outer space just in case.

Be Nice

What a shelf system! Photo by Peter Skiera.

Speaking of playing nice, the most important Bluetooth test was my Dayton Audio HTA100 hybrid tube integrated amplifier which has a Bluetooth receiver. My Sound Burger refused to pair and connect to it despite repeated attempts and with it literally sitting right next to my integrated amp. This was incredibly disappointing because the HTA100 is my primary audio system which I use daily. Upon further investigation, it turned out my HTA100 was connecting to my Vizio TV’s Bluetooth even though my TV was totally turned off (not in standby)! Huh? I went into the Vizio’s settings menu and instructed the TV to forget the HTA100. Once I did that, the Sound Burger paired and connected to the HTA100 within seconds and remained connected. It then connected automatically every time I used it. Double yay!

What Do You Like On Your Burger?

I was in a jazzy and bluesy mood so I began by playing a few tracks off of Richie Garcia’s vintage “A Message from Garcia” (Modern Harmonic MH-8078). This mono album from 1956 is not exactly the most vibrant recording, but it was enjoyable on the Burger nonetheless.

From there, I turned to the fantastic “Nina Simone Sings the Blues” (RCA LSP-3789). I bought this record a number of years ago through Vinyl Me Please but had never listened to it for various reasons. Now I know what I was missing. The Sound Burger did it justice and if it had a “repeat” function I would’ve used it.

I turned up the heat even more when I put on “The Drifter” by Mike Flanigin (Black Betty BBST-4068). Believe me when I say there isn’t a bad track on this album. When “Nina” began to play, I cranked up my integrated amp’s volume up to 45% and closed my eyes. It was a Sound Burger in paradise. Vocals were clear and strong, the bass was powerful, and I could hear each individual instrument.

To wind things down, I played my near mint copy of Shadowfax’s “The Dreams of Children” LP (Windham Hill WH-1038). Despite the recording being 38 years old, the music sounded perfect. I’m well acquainted with this record and I was pleased with everything I had heard.

Like A Version

The Sound Burger’s Bluetooth transmitter is version 5.2 which is one level below the latest 5.3 version. There’s not a lot of difference between versions 5.2 and 5.3, but 5.2 is superior to older Bluetooth iterations…version 5.2 is more stable and has improved latency (delay). It also requires less power in order to maximize battery playback time which AT puts at 12 hours on a full Burger charge (a USB-C charging cable is included).

Juice Me Up

While I’m on the battery topic, major kudos to AT for making the 2100mAh battery user replaceable. AT doesn’t yet sell replacement batteries but generic replacements can be easily sourced if you get desperate. I’m tired of Bluetooth devices with built-in batteries that aren’t user replaceable, requiring you to dispose of them (and the money you paid for them) when the batteries are spent.

Hum Along

If you want the best sound reproduction, there’s always the old-fashioned wired option via Sound Burger’s 3.5 mm line out (a short, inexpensive audio cable is included). Again, make sure whatever audio device you’re connecting to has a volume control. I need the wireless option since my HTA100 only has one set of analog inputs and they’re taken up by my cable box. One minor complaint- The Sound Burger has a built-in phono pre-amplifier allowing it to be conveniently connected to an auxiliary input. The problem is if you have a stereo receiver, integrated amplifier, powered speakers, etc., that has a dedicated phono input like my HTA100 does, there’s no way to defeat the Sound Burger’s internal pre-amp, meaning you can only connect it to an aux input. There’s also no ground screw on the Sound Burger, but so far, I haven’t noticed a hum problem.

Get To the Point

One of the keys to a turntable’s sound is its cartridge and stylus. In the Sound Burger’s case it’s the moving magnet ATN3600L which retails for $24 and is described by AT as good for “casual listening”. It’s the stock cartridge used on many budget turntables but don’t be put off by that. The ATN3600L enjoys a solid reputation in audio circles for its overall sound quality and tracking, with some claiming it sounds as good as cartridges many times its price. To my ears, it sounds good if slightly bright and aggressive. Regardless, it’ll have to do because there’s no upgrade path. But let’s be honest…the Sound Burger is not an audiophile piece of equipment, nor does it claim to be. Yet I have no complaints when it comes to its sound considering its price point and what it is…a Burger, not a Kobe A5 Wagyu Tomahawk steak.

Where’s The Beef?

Since the Sound Burger only weighs about 8 times that of a McDonalds’ quarter pounder, it’s very susceptible to vibration. Tap on its surface while it’s playing a record and expect to hear a corresponding loud pop from whatever you’re listening to it on. It’s too bad AT didn’t add some weight inside like a hunk of steel for a little more damping and a more quality feel, though I suppose extra weight would be counter to a product designed to be portable.

While we’re on the topic of touch, the Sound Burger’s plastic exterior is smooth and slippery…not the ideal surface for a portable device. Granted, it has a small handle on the back, but whenever I moved it, I instinctively lifted and carried it. I didn’t want it swinging around carefree from its handle and potentially banging into something. A rubberized coating and/or knurled areas to provide a good grip would’ve been appreciated. As a side note, in a couple of weeks I’ll be evaluating a generic carrying case.

Getting Technical

May the tracking force be with you. Photo by Peter Skiera.

Tracking force is the weight required for the stylus to follow the grooves in the record. Too little weight and the tone arm will lift off the record. Too much weight and the sound will be distorted and you could damage your record and stylus. I measured my Burger’s tracking force at 3.35 grams straight out of the box. The ATN3600L user manual recommends 3.0-4.0 grams with 3.5 grams being standard. Mine is within spec but I would’ve preferred it at least meet the standard and there isn’t any way to adjust the weight.

I Got Screwed

The Sound Burger’s two speed adjustment pots. Photo by Peter Skiera.

As you can see from the above graph, my Burger was exceeding the speed limit with 33 1/3 averaging 34.05 RPM, while 45 RPM topped out at 46.24 RPM. Being the anal audiophile that I am (some would say “anal audiophile” is being redundant), I decided to manually adjust the speeds using the 2 access holes on the bottom of the Burger along with a small, flat-head screwdriver. I was successful at adjusting the 45 RPM speed but 33 proved more elusive. The tiny white plastic adjustment piece broke off the potentiometer before I could finish my tinkering. As a result, 33 1/3 is now stuck at 27 RPM rendering it unusable (I’m in the process of getting my Burger repaired through Audio-Technica). Luckily, I saved this speed adjustment task for last. I had already completed my evaluation before tackling the speed issue. My advice to you is unless the speeds are way off, leave the trim pots alone. They’re too delicate to fiddle with and it isn’t worth the risk.

De Colores

Some like their Burger pink in the middle. Photo from AT’s website.

Let’s switch gears from technical to color, or Technicolor. The Sound Burger was first released in a limited-edition red version last November to celebrate AT’s 60th Anniversary and the 7,000 Burgers sold out. Earlier this year the Burger was made available in black and white, and more recently, in yellow, all priced at $199 each. Had it been me, I would’ve made the limited edition in silver which was the original and only color when it debuted back in 1983 as “Mister Disc” in the USA. I would’ve made the red color part of the regular line up. AT would’ve sold many more than 7,000 if red had been a standard color. It’s also a great color for marketing purposes.

“Mister Disc” was a weird name but it fit the era. Besides, the name “Walkman” had already been taken. In the UK and Japan, it was called the “Sound Burger”, and that’s the name AT used for this 2023 reboot. It’s certainly a more playful name though equally weird. Perhaps it was intended to hint at the fun that was in store for the new generation of Burger lovers.

61 Years and Counting

AT’s AT-LP2022 acrylic turntable is clearly different. Photo from AT’s website.

As I mentioned, AT has been around for almost as long as I have. It was founded by Hideo Matsushita in Tokyo in 1962. It was initially a phono cartridge manufacturer starting with the AT-1, the first affordable phono cartridge. Today, the company’s product lineup includes an impressive selection of turntables, headphones, microphones, professional equipment, and of course, phono cartridges. Their limited- edition AT-LP2022 turntable is a head turner with its dense, clear acrylic chassis, platter, and Shibata stylus. At $1,200, it’s a tad more expensive than the $199 Sound Burger.

Need A Lift?

Take care when lifting the Sound Burger’s stylus. Photo by Peter Skiera.

From comments I’ve heard and read, handling the tone arm is apparently the most difficult part of using the Sound Burger. There’s no space for a tone arm lift, so it has to be accomplished manually. I’m right- handed and I have a slight shake in my right hand, which hopefully is nothing serious, yet I had no problem managing the tone arm. There was only 1 instance when I slightly scraped the stylus on the record while lifting the tone arm. That said, I can see it being a little challenging for some users.

Light Me Up

I admit I’m a closet light freak. I love lights on my audio gear and I suspect I’m not alone. We’re part of the great silent audiophile majority. Lights might not make any contribution to sound quality but they definitely raise the fun factor. The Sound Burger has small power/charging/BT and speed lights, but the speed light only comes on when it’s set to 45 RPM. Had I been the Product Manager for this model (AT, if you’re listening, I’m available), I would’ve made the speed LED bi-colored so it would be one color for 33 1/3 and another color for 45 RPM. That way there would be a light on regardless of the speed setting.

While we’re on the topic of lights, I would’ve placed a single blue LED in the center of the Bluetooth pairing button instead of making the power light do triple duty. I also would’ve back lighted the “Sound Burger” name whenever the unit was on. Did I mention I love lights?

Have It Your Way

I’m not done. I would’ve included a downward firing LED mounted to the outside of the lid above the record on the side that houses the tone arm. Not only would it look very cool illuminating a spinning record, it would also aid in placing the stylus if you were looking to drop it on a specific track. The cost of these additions would’ve been minimal as would the power to light them, it would’ve further distinguished the Burger from the original model, and it would’ve multiplied the fun factory by ten.

May I Take Your Order?

Put simply, Audio-Technica‘s Sound Burger is the Happy Meal of portable turntables. Like fast-food, it’s convenient, fun, provides instant gratification, and sounds delicious. It even has a cover to prevent one’s drool from coating the platter. In a word, you’ll flip over the Sound Burger. Get it? Flip? Burger? See what I did there?

Summer Sounds On A C-Note

Last year around this time I reviewed several portable Bluetooth speakers to help you take your favorite music outdoors as summer approached. This time I’m going old school and focusing on wired outdoor speakers.

Wireless outdoor speakers are all the rage nowadays, so why go wired? I ruled out outdoor Bluetooth speakers because of the potential for unreliable reception and running down my smartphone’s battery. My Wi-Fi coverage outside is shaky at best, so that took Wi-Fi speakers out of the equation. Either would also need to get power which wasn’t an option in my particular installation. Last but not least, I wanted to keep my budget at around $100 which would be tough for good sounding wireless speakers.

Mind you, wired outdoor speakers can be very expensive. High end speaker company Revel makes a pair of outdoor speakers that sell for almost $1,000. B&W has a set for $800. Coastal Source makes a “landscape speaker” with a built-in subwoofer for a cool $3,500 each. You can even buy an outdoor subwoofer if you really want to rock your rock garden. In my case, I wasn’t trying to have my speakers show up on a Richter scale. Would I be able to find a set of good sounding outdoor speakers for $100, or was I setting myself up for certain failure?

Speaker Overboard!

The Outdoor by Henry Kloss. Image from The Outdoor user manual.

My first experience with an outdoor speaker was with Massachusetts-based speaker company Cambridge SoundWorks at their South Portland, Maine store where I was the Assistant Manager. We made (in our Massachusetts factory) an outdoor speaker model called simply “The Outdoor” by Henry Kloss. I don’t remember how much it sold for, but I do remember being told a story about a customer who wrote us a letter (back when people still wrote letters) about his speakers which he had mounted on his boat. One of the speakers became dislodged and fell into the open water as his boat was moving at a good clip. He recounted how he observed the speaker violently bouncing around in the ocean as he brought his boat to a stop. Still connected to its speaker wire, he pulled the speaker in as if reeling in a fish on the end of a fishing line. When he brought it back on board the speaker was still playing music! He wiped it off and returned it back to its original location, making sure it was secure.

Rock Solid Sound

The very first set of wired outdoor speakers I ever owned was a pair of B&W (B&W not BMW) Rock Solid Monitors. Rock Solid was B&W’s entry level plastic speaker line made in Japan. I worked for B&W at the time and fell so much in love with the cute indoor/outdoor speakers that I bought two pair. They sounded fantastic, reaching down to 50Hz when wall mounted, and had integrated metal stands that provided uniquely generous articulation from walls and ceilings. They even included little metal mesh bug screens you could pop in the front bass ports to prevent creepy crawlies from making their home inside the speaker housings. I recall sitting at an outdoor bar on Grand Cayman Island while on vacation almost 2 decades ago and listening to music. I looked up – and you guessed it – it was a pair of Rock Solid Monitors cranking out the tunes. Such was the world-wide popularity of these monitors which you can still find used on eBay.

Natural Sound?

The Yamaha NS-AW350. Image from

My next pair of wired outdoor speakers was a set of Yamaha NS-AW350W’s. These were a considerable step-down from my Rock Solid speakers, both acoustically and cosmetically, but my budget was much smaller and I needed speakers with a smaller footprint. Frankly, they didn’t sound all that great, especially in the bass department, and their wall mounts only had 2 positions which forced me to choose between one or the other. But they allowed me to get my music outside for a reasonable price and they fit the only space I could install them.

Something I’ve never owned is a pair of those so-called “rock speakers”. They tend to sound as bad as they look. I also wasn’t interested in having the sound directed at my fibula instead of my ears, or serenading my plants which are challenged enough as it is with me as their caretaker. Funny enough, I’ve never seen a real rock that plays music and has perforations in a circular pattern.

Speaker Who?

This summer I wanted to find the holy grail of outdoor wired speakers…good sounding speakers (including decent bass) with full motion mounts for around one hundred bucks. I briefly considered buying a used set of Rock Solid Monitors but they were beyond my budget, as were B&W’s LM1’s which replaced the Rock Solid Monitor. I read loads of outdoor speaker reviews, but most of the $100 or less models failed the sound quality test and/or included wall mounts that were a joke. Then I stumbled upon the OSD Audio AP650.

I’ve worked in consumer audio for over 20 years and to be honest, I’d never heard of OSD (Outdoor Speaker Depot) before. Located in Brea, California, OSD does their design work in the USA while their manufacturing is done in Asia. They operate a 45,000 sq. ft. distribution center so whatever you order from them is probably in stock. In addition to a variety of outdoor speaker models, OSD also offers home speakers, amplifiers, mounts, audio cables, and even speaker wire in bulk.

The thought of buying speakers from an audio company with the word “Depot” in its name wasn’t comforting, but there were several things that sold me on the AP650 besides their price. As I mentioned, bass was important to me, and OSD claims the AP650’s bass response is rated down to 35Hz. I didn’t have a way to verify that but even if they’re off by 20Hz, which would be unusual, that’s still good bass for a budget outdoor speaker. The sensitivity is listed at 90dB and efficiency was another key spec since I’m using a low power amplifier. The AP650’s come with 180 degree swivel and 60 degree tilt wall brackets. This was critical because my speakers would be mounted up high and I needed the ability to both angle the speakers downward and toe them in in order to direct the sound at my seating area. Most wall mounts let you to do one or the other depending on whether you mount the speakers vertically or horizontally. Few mounts in this price range allow you to adjust both without having to commit to the orientation of the speaker.

Rock, Scissors, Paper

One thing of concern was the fact that the AP650’s use 6.5” paper cone woofers. Paper cones can yield excellent sound quality and have been used since the advent of loudspeakers, but paper isn’t the best material for outdoor use for obvious reasons. However, OSD treats the AP650’s woofer cones to make them water resistant. With their 23 engineers, you’d think they could’ve managed to obtain similar acoustic performance using polypropylene woofers like almost every other outdoor speaker employs. The speaker housings are sealed (no bass ports), yet only carry an IP54 (Ingress Protection) rating, which isn’t great for an outdoor product. They’ll be under eaves and they won’t be getting hit with a hose or splashes from a pool which should help their longevity. Only time will tell how well they’ll hold up.

Best Value

Disappointingly, my search results didn’t reveal a lot of reviews of the AP650. I found a couple of reviews on YouTube but they were for OSD’s Bluetooth version of these speakers. On Amazon, the AP650’s are rated 4.6 out of 5 stars with such positive comments as, “I would buy this setup again 100 times over”, “these speakers sound amazing”, and “bass is much tighter.” OSD’s website also had reviews but I suspect they only posted the positive ones. Comments ranged from “awesome sound” to ” very happy with them” to “exactly what I was looking for”. The New York Times compared several different outdoor models and rated the AP650’s their best buy, calling them “the best value we’ve found in an outdoor pair. Their clarity beats anything we’ve heard from other models priced under $200 a pair. And they have a full, powerful sound that can easily fill an outdoor space, up to about 1,500 square feet. The AP650 speakers have enough bass for R&B, hip-hop, and rock music…This pair is also better made than most under-$200 outdoor speakers, with a thicker enclosure and a sturdy, powder-coated mounting bracket.”

I should point out that the AP650’s are listed for $195 per pair on Amazon which was almost double my budget. I ended up purchasing mine on eBay directly from OSD for $110 for the pair including shipping. I don’t understand why Outdoor Speaker Depot significantly undercuts their own prices on their website and in their Amazon listing, but ours is not to reason why. Outdoor Speaker Depot also offers the AP850 which boast 8” woofers and bass rated down to 32Hz, but at $300.pair, that wasn’t going to happen.

DIY Speaker Install

You can tell I’m not married because this mess would rate a zero on the Wife Acceptance Factor. Photo by Peter Skiera.

As I awaited the arrival of my new speakers, I set out to get my wiring in place. I wasn’t able to run speaker wire direct to my source, so I dug out my Rocketfish RF-WRSK18 2.4GHz wireless audio transmitter which I had packed away in my garage and connected it to the speaker outputs of my Dayton Audio HTA100 hybrid vacuum tube integrated amplifier. I used the HTA100 because it was my only option, not because I wanted a tube sound outdoors. I wall mounted the companion Rocketfish receiver (which has its own volume control) 19’ away from the transmitter and ran 16-gauge speaker wire from it to the places where I was going to mount each speaker outside. This required drilling a 5” deep hole through an exterior wall to get the speaker wire outside (which I later sealed up with caulk).

Hang In There

Once I received my speakers, I installed the included wall mounts into studs and then mounted the speakers making sure to position them so they flooded the seating area with music. This wasn’t easy because the speakers weigh 9 pounds each, so juggling one in one hand with a screwdriver in the other while standing on a ladder was somewhat precarious. At nearly a foot tall and 8” wide, these speakers aren’t compact, so be certain your space will accommodate them. If you want outdoor speakers that blend into the background, these aren’t for you.

It’s A Cover Up

Interestingly, both speakers came supplied with matching removable rear plastic covers with an exit for the speaker wire to help protect the binding posts from the elements. They also lent the speakers a nice clean look even though no one will probably ever notice them. Of course, the covers make no contribution to the sound quality, but it’s these little touches that let you know OSD’s designers were paying attention. I’ve never encountered such a feature on any other outdoor speaker, at least not in this price range.

My speakers also came with a 70 volt adjustment just above the biding posts which is typically reserved for commercial applications where many speakers are daisy chained together to cover very large spaces. There’s an 8 ohm setting if you’re just using one stereo pair, as in my case, but you can buy the speakers without the 70 volt option if you prefer.

Hi-fi outside: The AP650 outdoor speakers. Photo by Peter Skiera.

After breaking the speakers in for a couple weeks, my overall impression is very favorable. My Rocketfish transmitter is probably a weak link in the audio chain, but for my purposes, the sound quality is more than acceptable, including the bass. My HTA100 has Bluetooth 5.0 so I’m able to stream from the Spotify app and hear it on my outdoor speakers, but mostly I take the audio from my cable’s commercial-free music channels. This also allows me to listen to baseball games, news, etc. while outside. My patio is about as modest as they come…no hot tub, no in ground pool, no outdoor kitchen, no motorized awning, and no outdoor TV, but I still enjoy relaxing outside. Being able to listen to music on quality stereo speakers takes it to a whole other level. Considering what I paid, I think I got a bargain, which doesn’t happen very often in consumer audio. Ready, set, summer.

Full disclosure: I didn’t get the OSD AP650’s for free or at a discount in return for my review nor do I receive a commission should you buy them.

For The Vinyl Lover Who Has Everything

The Vylümi Shine Pro.

What? Vylümi Shine Pro safely backlights colored vinyl records allowing you to display them like works of art.

How much? Vylumi Shine costs $60 and the Shine Pro is $120 plus shipping.

Conclusion? It won’t fit in a Christmas stocking but get it anyway.


Black Is Beautiful

Looking for that elusive gift for the record collector who has everything? Before we get into the details of this device that illuminates colored vinyl, a little background is in order.

Records are made with PVC pellets (which are naturally slightly milky-white in color) that have been mixed with black carbon which is gives them their shiny black color. The black carbon also fills in imperfections and adds strength and rigidity which makes the record last longer. This is important because, unlike a CD, cassette tape, or digital music file, a record album degrades each time you play it.

Another thing basic black has going for it is that the quality of black vinyl records tends to be high because it’s the industry standard…they’ve been producing them that way since the advent of the vinyl record. As a result, the quality of black records is remarkably consistent. The black color also makes it easier to spot imperfections during quality control inspections.

Color Me Impressed

Colored vinyl, on the other hand, uses PVC pellets mixed with dyes. In addition to records made using a single, non-black color, there are variations on the colored vinyl theme like multicolored, split color, smoked, marbled, and splattered. Yes, I’m talking about records, not meat or cheese. By the way, don’t confuse any of these variants with picture discs which are a whole other story and tend not to sound as good or last as long as colored or black vinyl.

A Little History

Colored vinyl records didn’t start with the vinyl LP. Some 78 RPM titles dating back to 1917 were colored, starting with a Vocalion Records release that was a reddish-rust colored shellac. Perhaps not the most appealing color choice, but it served its purpose of making their records stand out. I believe the first prolific use of colored vinyl by a major label was RCA Victor’s introduction of the 45 RPM single in 1949. To give the new format a little extra excitement, each genre had its own color. For example, country music used green-colored vinyl, classical used red, children’s recordings used yellow, while pop music stuck with basic black.

The Sound of Color

There’s a school of thought that says not all colored vinyl is created equal. That is to say, certain record colors may not sound as good as others upon playback, or as good as your standard carbon black record. It’s strange to think that color could impact sound, but it can. In fact, one could argue the more colors present in the vinyl, the worse the sound might be because of all of the foreign ingredients. There are even glow-in-the-dark records, though I don’t know anyone who plays their records in total darkness. I’ve read these are noisier than their black and colored brethren, but I can’t personally attest to that since I don’t own any. It would follow, then, that a transparent clear record would sound better than a colored vinyl record (except for black).

Do You Hear What I Hear?

If I played a colored vinyl record for you, immediately followed by the identical recording pressed on black vinyl, would you hear any difference? I suspect most people wouldn’t, but if there was an overt difference, it could just as well be attributed to the manufacturing process rather than the color of the vinyl. If the record plant doesn’t have much experience pressing colored vinyl, that won’t help either. Regardless, most record enthusiasts don’t buy colored vinyl records because they think they sound superior. They buy them for their unique appearance and collectibility, especially since many colored vinyl titles are produced in limited batches.

Price Check

Speaking of limited quantities, that, along with the cost of the dyed pellets, tend to make colored vinyl titles more expensive. So, you’re paying more for a record that technically probably won’t have the same longevity as less expensive black vinyl and possibly not as good sound quality. Mind you, there are plenty of black vinyl titles that can be quite pricey in their own right.

In Living Color

If you want to add some colored vinyl to your collection you don’t need to search very hard. Some record labels specialize in colored vinyl like Third Man Records, Real Gone Music, Enjoy The Ride Records, Sundazed Music, Wax Mage, and WaxWork Records. Major retailers like Barnes & Noble, Urban Outfitters, and Newbury Comics sell colored vinyl, some of which are exclusive to them. Even record clubs like Vinyl Me Please and Vinyl Moon release titles on colored vinyl. Yes, Virginia, there are record clubs.

If you want to go off the deep end, you’ll find records that go way beyond colors. Romanus Records, for example, has pressed records with different kinds of material sandwiched between the 2 sides including kitty litter, razor blades, sand, gunpowder, colored liquid, LEDs, and even pieces of Doritos chips! I wonder how some of those records would look with colored lights behind them. I was delaying this article to be able to display my “snow globe variant” Scrooged LP soundtrack I ordered more than 6 months ago. It contains a clear liquid with sparkles inside. I decided to go forward with my article rather than continue to wait. Such special releases require more time since they’re much more complicated to produce.

The Vinyl Verdict

You’ve heard the saying, “Once you go black, you never go back.” Somehow, I don’t think that phrase was about records, but it might be equally applicable. The absence of black carbon likely means colored vinyl records won’t have the same strength and longevity as their black counterparts and may not sound as good. That said, unless they’re abused, most colored vinyl records should last long enough and sound good enough for the average record enthusiast. If sound quality is of the utmost importance, you’re probably better off playing it safe with good old, boring black vinyl. On the other hand, if seeing colors and patterns spin on your turntable puts a smile on your face and you’re enthralled by the art, go for it. After all, records have the potential of being the most visual of all music storage formats.

Show Off

Colored vinyl is meant to be seen and heard. If you’ve got an album you especially love the color of, why hide it inside a cardboard jacket? Sure, you could frame it, but that’s not very exciting, and it prevents you from being able to easily play it. What if there was a product that allowed you to safely display your colored vinyl, backwash them in light, and easily access them for playback? Well, there is.

Let There Be Light

Vylumi Shine and the Shine Pro do just that. Andrew Boudreau came up with the idea and had his final design completed in 6 months. He hand-assembles each one out of his home in Atlanta, Georgia and sells them on his recently revamped website and on Etsy. The two models backlight a record to make its color(s) pop. Simply place the record over the center nub and turn the light on. Voila! Instant glowing artwork. The record “floats” so you don’t have to worry about it making contact with the surface and getting scratched. And the LED that illuminates the record never gets hot enough to warp the record, so no worries there. The result is beautifully mesmerizing.

I got in touch with Boudreau to ask him some questions about his unique invention:

Peter: What gave you the idea for Vylumi Shine?

Andrew: It all started in late 2021 when I picked up my first picture disk. I was searching online for ways to display it since it’s widely known the audio quality on all of them are notoriously bad and I couldn’t find anything that didn’t have a massive picture frame as part of the display. I knew a good friend of mine had a 3D printer so I ran him through an idea of what I now call the ‘Nub.” It’s a very minimalist design and is simply a rod the size of the record spindle that angles up to safely keep the record in place and that’s attached to a base plate. I was using a simple command strip to test hanging a few on the wall and while I was thumbing through my collection I thought: “I wonder what else would look good hanging on the wall,” so I grabbed a copy of Cowboy Bebop that I knew had a nice colored marble to it and hung that on the wall to see how it looked. It looked okay, but a bit lifeless, so on a whim I brought it over to an outside window to get some light on it and it came to life! That’s when the light bulb(s) went off (dad joke, apologies). It just dawned on me that I had so many of these color variants in my collection, and they were just spending their lives tucked away in their sleeves on the shelf. So, I built my first prototype out of cardboard, a battery powered LED light string, and the nub and just started putting records on it to see how they looked. It was very basic, but the idea worked. 4 prototypes later I had a design I was really proud of and started showing people in February of 2022. Everyone I showed wanted one for themselves so I started making a few. I opened the Etsy store in March of 2022 and my own website in June. So far, I’m at 300 units sold worldwide and I can’t explain how proud and fulfilling it is to see my customers showing off their collections on social media.

Peter: You source the parts and assemble the units by hand in your spare time? 

Andrew: The electronics I source through two separate companies and I’m trying to narrow that down to one moving forward. I do that for a few reasons; First, it allows me to be more nimble when new technologies emerge. Secondly, after putting in an inquiry with a product design company, I learned that it would take about $200,000 just to get custom electronics and molds designed and the same, if not more, to actually get them produced. I’m very proud that the structural materials are all made here in Georgia. Very early on I had run this idea by my neighbor, as he likes to tinker and is generally handy. I came to him with the problem of properly diffusing the light to see if he might have any ideas. He operates a company that specializes in large scale vinyl wraps and signage projects for conventions and airports, so I thought he might have some ideas and I recalled that he had a few CNC machines that weren’t getting a lot of use because Covid had really hit their business pretty hard. I drew some designs on some printer paper and he cut those out on the CNC machines, and to this day his company cuts all of the structural parts. As mentioned above, a friend of mine makes the nub on this 3D printer and I’m able to pay him a fair price per batch he prints. But to the other part of your question, after I get my daughter to bed and my wife settles into a book, I head to the basement and assemble these by hand still. I’ve had to make a few tools to speed up assembly and help to standardize the sizes of a few components, but I can’t explain how much I love doing this!

Peter: Does it work with picture discs? 

Andrew: You can certainly display a picture disk on a Vylümi, but sadly, picture disks are all opaque and won’t let any light through. 

Peter: You have a Patent pending? 

Andrew: I do!  I have both Trademarks and Patents pending for this as of this last summer. 

Peter: Do you own a lot of colored vinyl or records in general? What’s your favorite-colored vinyl title? 

Andrew: I’ve been trying to catalogue my collection and I think I have about 1,000 in my collection right now. I’ve been building a vinyl collection since 2008 when I invested in my first Hi-fi setup and started to get into finding color variants 4-5 years ago. Color variants are probably 10% of my collection and I didn’t get into collecting the more boutique pressings from Wax Mage and others until I came up with this idea and found them through my research. My favorite though? That’s like picking your favorite child! My recent favorite is a pressing from Glory or Death Records by Great Electric Quest (which is actually his band). It’s a beautiful party monster and really transforms with the Vylümi to look like a sheet of elegant stained glass…It also glows in the dark as a bonus!

Peter: What’s the rarest or most expensive record you own? 

Andrew: This little invention has introduced me to a lot of amazing people in the industry. Pretty early on I contacted the folks at Wax Mage/Gotta Groove, Wax Vessel, SlyVinyl, Heathen HandMade Records, Romanus Records, and Plastikat Deviations to get their feedback on my idea and early products since they make the hand-crafted art my audience is collecting. Recently, Matt Ortt at Plastikat surprised me with one of his liquid-filled records that is a complete one-off. It was made for the owner of Glory or Death Records and is the first liquid filled that has two separate chambers of liquid in it. A portion of that liquid is black, so when it’s on the turn-table spinning, it spreads out pretty evenly with centrifugal force that it just isn’t awesome eye candy like the rest of his stuff. He put it on his Vylümi and it just transformed. He dropped me a note that said this album looks best when lit up, and we (he and Buddy from Glory or Death Records) thought you should be the rightful owner of it. That about made me cry, I am so honored to have it and it is by far the most-rare album I own. 

Peter: What brand and model turntable(s) do you use?

Andrew: For my 40th [Birthday] I was able to purchase a Rega P6 and have a Dynavector 10×5 with a ruby cantilever and optimized contour nude contact line diamond tip from Sound-Smith after bending the original cantilever in a cleaning accident 3 months into owning it. That one hurt the soul, but I can’t speak highly enough of the crew at Sound-Smith and their craftsmanship they put into repairs and upgrades.   

Peter: What’s your professional background? 

Andrew: My day job is and has always been in technology sales. I get to be a nerd all day long and I have to constantly learn about what’s new in the market, and my customers are always bringing me difficult problems to solve. It’s a pretty demanding, high stress job, so sitting down to spin a record at night has always been my way to unwind. I’m certainly not an engineer or someone who is crafty/handy, so the fact I was able to come this far with an idea is a miracle unto itself.  

Peter: What kind of music do you usually listen to?

Andrew: My tastes are certainly firmly on the rock side of the spectrum. I can be found listening to your typical classic rock albums, but spend most of my time reliving my high-school days with grunge/Alt music from the 90s.  

Peter: Anything else to add about the Vylumi Shine/Pro? 

Andrew: I would just like to thank everyone for their kindness and support (!), and thank you Peter for taking the time to talk with me.  This has been an unintended and amazing journey. I never thought this idea would take off in the way that it has and all of my customers have been so patient and understanding of the fact that I’m a one-man shop doing this in my spare time. The vinyl community has been very generous to me over the years and I’m so thankful I can provide a little something back. Thank you all for the support and I can’t wait to see where this journey goes! 

Picture This

An Instagram photo of the Vylumi Shine in action.

I found splattered vinyl to look the most impressive with Shine Pro. Colored vinyl that’s all one color looked like a giant-colored spotlight. As it turned out, I only had one splatter-colored record in my small LP collection. Its base color was transparent which meant I could make it whatever color I wanted with the Vylumi Shine Pro’s light, which was very cool. You can see more impressive Shine Pro-worthy pictures on Boudreau’s website, Instagram, tiktok, Etsy, and Facebook (links provided at the end of this article).

Size Matters

If you happen to have a few colored 45 RPM singles or 10″ records in your collection, Boudreau has you covered. For $20 you can get a set of adapters that fit both of those sizes, though the adapters can only be used in conjunction with the “dust cover” which is an additional $30.

Ask The Manager

As a Product Manager, part of my job involves finding problems with a product before it goes into production and coming up with ways to improve it. In the case of the Vylumi Shine Pro, I have a couple of suggestions for improvements and enhancements.

To start with, being able to anchor the base or give it some weight would be great, as the base is very light weight since it’s just a thin, empty plastic case with LEDs. If you use the wired remote instead of the app as I did, you must be very careful not to accidentally yank the base.

Getting my record off of the center nub was rather difficult. I had to pull the record to the point of bending the sides of the LP. Due to the nub being a black or dark brown color, I didn’t notice until later that it’s actually positioned at an upward angle instead of straight so the record doesn’t fall off easily. Had I known to pull upward instead of straight, it would have been a bit easier to remove the LPs. Still, Boudreau has since modified the nub in production to make it a slightly smaller diameter. I’d also suggest putting a radius on the nub. No sharp edges in close proximity to records!

It would be nice if at least the Pro model could be wall mounted. Boudreau told me one can easily glue a saw tooth hanger on the back but the problem is the dangling wires from the combined wired remote control/power supply. His first-generation models were battery powered and could thus be wall mounted. I assume a built-in Li-Ion battery rechargeable version would be too expensive to make.

What I would really like to see the Pro do is what records are supposed to do- spin. Seeing colored vinyl come alive through light is amazing, but having the record actually rotate (not necessarily at 33 1/3) would be very cool and more engaging, especially if the record was liquid-filled. Without a doubt, this would push the cost higher, perhaps to the point of turning most buyers off. If you’re tempted to manually spin your record on this device, Boudreau warns users against this or else the 3D-printed nub will eventually become sawed off.

Don’t Try This At Home

The Shine Lite sells for $60 while the Pro goes for twice that plus shipping (the Pro is on sale as of this writing). Frankly, both models look remarkably simple. Being the cheap and creative guy I am, I tried to think of a less expensive way to accomplish the same thing, which is also part of a Product Manager’s responsibilities. Since I was a kid, I’ve had a bit of MacGyver in me…spontaneously creating things out of duct tape and tampons, although nothing explosive. I remember one Halloween I secured rope from the kitchen window of our second-floor apartment down to a chain link fence adjacent to the sidewalk in front of our house. I cut a small hole in the top of a white pillow case, slipped the top of a metal coat hanger through the hole, and drew two eyes and a mouth with a black maker to make it look like a ghost. I tied a second rope onto the hook of the coat hanger in order to slide it up and down the main rope. As a final touch to my crowning achievement, I hung a flashlight from the coat hanger inside the pillow case to illuminate my ghost, hung it on the rope, and slid it up and down as the trick or treaters made their way in and out of our apartment house. I was quite proud of my creation and the costumed, candy-hungry visitors appeared equally impressed. A few years ago, I saw a very similar contraption in a catalog, albeit much more refined. That guy probably owns his own island now. But as usual, I digress.

Returning to my MacGyver LP light, I took a cheap picture stand that was collecting dust in a drawer and placed one of my colored vinyl records on it. I then backlighted the record with a Remon 25-watt LED spotlight I bought two years ago on Amazon for $29 (which has since been discontinued) to light my vintage aluminum Christmas tree. The light included a remote control that allows the light’s brightness and colors to be adjusted similar to the Vylumi Pro’s remote, although it doesn’t have a built-in microphone to flash to the beat of music like the Pro can. My color contraption created a similar effect as the Pro, but the stand could be seen behind the record, it risked scratching the record, and the spotlight got hot enough to make me concerned about the record possibly warping. It also sent the light all over the place rather than containing it just to the record itself. The Lite and Pro each cost significantly more than my Frankenstein light, but they accomplish the task more effectively, safely, and elegantly.

Wow. Photo from Instagram.

If you don’t need the additional control the Vylumi Shine Pro provides, like thousands of color options, 100 dim levels, a remote, free app (by a 3rd party), a timer, the ability to group other Pros, and Siri/Alexa compatibility, you can save some dough and stick with the more basic Shine. Either model is a fun and safe way to display and share your beloved-colored vinyl. If you’re looking for a gift this holiday for the vinyl lover who has everything, this should do it.

Bluetooth Speaker Round-Up

If you’re like me, you can’t be away from your tunes for too long, especially when you’re outdoors. Whether it’s hosting a backyard cookout, gardening, or just washing the car, having my favorite music playing nearby is always high on my checklist. With the weather improving every day, now’s the time to start thinking about a portable Bluetooth speaker for outside listening or when you’re on the go.

There’s a glut of portable Bluetooth speakers of all shapes, sizes, and price points. Just about any company can make a Bluetooth speaker and it seems just about every company does these days. Bluetooth speakers have come a long way as far as sound quality and battery life are concerned, but making one that sounds good and is fun to use is not easy. For this month’s blog post I undertake my first-ever hardware review…a roundup of four fun portable Bluetooth speakers…some old, some new, all under $160, and all providing musical fun in the summer sun.

That’s no optical illusion. The M90 Mini Blaster is really that small. Photo by Peter Skiera.

Model: M90 Mini Blaster

Brand: New Wave Toys

Sound: 7/10

Fun Factor: 10/10

Playback time: 40 hours

Bluetooth Version: 5.1

Warranty: 100 days

Price: $159.99

The M90 Mini Blaster by New Wave Toys in North Hollywood, CA is the newest model of my roundup. New Wave is known for their accurate reproductions of classic video arcade games. Their arcade games are considerably smaller than the originals that inspired them, but they look incredibly authentic and they actually work!

Almost 2 years ago, the company threw their miniature-sized hat in the crowded Bluetooth speaker ring, launching a Kickstarter crowdfunding campaign for their M90 Mini Blaster and M90 Micro Blaster (an even smaller version Bluetooth speaker). I was one of over 2,700 backers to receive my M90 Mini Blaster about 2 months ago and despite some issues, I haven’t been able to put it down.

Back To The Future

Rather than make a ho-hum-looking Bluetooth speaker, New Wave stuck with their 1980’s theme and designed a faithful reproduction of the legendary JVC RC-M90JW (known as “the king of boomboxes”) from 1981, albeit on a considerably smaller scale. I own a couple of working vintage boomboxes including the JVC RC-M90, and I can say with authority the company is to be congratulated on the job they did emulating the original boombox. New Wave must have invested an enormous amount of time studying the RC-M90 (presumably thanks to the boombox museum they reference in the user manual) to achieve such remarkable detail in the M90. The Mini Blaster may be small but it’s a big blast (from the past).

What’s In A Name

Don’t let New Wave Toys’ name fool you. The M90 Mini Blaster is no toy. In addition to Bluetooth 5.1, the 30-watt stereo M90 Mini Blaster houses two 3” full range speakers (the drivers in my version have “limited edition” blue-colored cones), a decent FM tuner with dual telescoping antennae (AM was disabled due to significant reception problems), a 3.5mm analog stereo input, a USB-A for playing music from a thumb drive or charging a smartphone, and a Micro SD card input. Frankly, had I been the Product Manager for this model, I would’ve left off the Micro SD card input and added other features that would’ve been more widely used and appreciated. But I’m not done. With it’s built-in microphone, the M90 Mini can be used as a good quality speaker phone. I tried it and the party on the other end commented that I sounded better than when I use only my phone. You can also pair two M90’s together to achieve true wireless stereo (TWS). A USB-C is on tap for charging the internal 20,000mA battery. That kind of battery capacity is unprecedented for a Bluetooth speaker of this size and price. According to the company, the M90 will play up to 40 hours on a single charge. The M90 Mini Blaster is indeed the Tesla of Bluetooth speakers.

New Wave made the M90 Mini Blaster even more special by including some very sweet accessories. There’s a mini wired remote control that works (also based on the original JVC wired remote), gnarled, aluminum knob expanders to provide a better grip of the very tiny bass, treble, and balance knobs (which actually work), and an adorable faux iconic Memorex cassette tape complete with blank stickers so you can label it “80s Mix Tape” (the cassette deck isn’t functional but the door opens to accommodate the tape). There’s even an optional soft, sleek, black custom carrying case in which to store your M90 Mini Blaster when you’re not using it (which I assure you won’t be very often).

“According to the company, the M90 will play up to 40 hours on a single charge. The M90 Mini Blaster is the Tesla of Bluetooth speakers.”

I’ve Got Issues

When a company that’s not an audio company dares to enter the audio field with their first audio product there are bound to be issues. The M90 is no exception. There’s prominent white noise in the background and the volume control isn’t gradual. The level choices are basically zero, medium, and high and nothing in between. Disappointingly, New Wave never apologized for the problems and actually told users to turn down the treble control if they found the white noise objectionable! They ended up issuing a firmware update in an attempt to improve the volume behavior, though the user feedback I’ve read on their campaign page isn’t favorable, including several units being rendered non-functional after the update, so I’ve refrained from updating mine. New Wave certainly never would’ve shipped their arcade games if they all had problems with their displays. Likewise, the M90 never should’ve shipped with these audio problems. To New Wave’s credit, they’ve voluntarily offered refunds to any Kickstarter backers who are unhappy, which they aren’t required to do. Even with these problems, wild horses couldn’t drag mine away from me.

There are other scalp-scratching decisions New Wave made like omitting a headphone jack, placing the Bluetooth status light on the back instead of the front, omitting a power light, leaving off a Loudness control like the original JVC boombox had (and which the M90 would’ve greatly benefited from), and always defaulting to Bluetooth mode rather than to the last mode used. Oh- and those cute little Vu meters on the front…they’re not load-bearing. I’ve said it already, but it bears repeating…I won’t allow these things to get in the way of me enjoying the M90 Mini Blaster.

One final bone of contention I’ll raise before stepping down from my soap box has to do with New Wave’s 100-day warranty which is standard for their product line. My 2-slice toaster made by a Chinese company I never heard of before, and which cost me a lot less than the M90, came with a 1-year warranty. The other models in my Bluetooth roundup cost quite a bit less than the M90 Mini Blaster, yet they all come with a one-year warranty. New Wave should have enough confidence in their own design and engineering, and respect for their customers’ hard-earned money, to stand behind their products for at least 12 months. I’ve worked for numerous audio companies including two small startups and none of them offered less than a 1-year warranty.

To be perfectly clear, the M90 sounds good, but there are other good sounding Bluetooth speakers on the market without audio issues that cost less. None, however, evoke 80’s boombox nostalgia like the M90 Mini Blaster. You simply won’t find anything else like it because no other company is crazy enough to try to do it. An original, working, vintage JVC RC-M90JW boombox will set you back several thousand dollars, but you can get this incredible smaller simulation for $159.99, whenever New Wave Toys gets them back in stock that is. Summer just got a whole lot funner.

The Wild Mini’s charm will rope you in. Photo by Peter Skiera.

Model: Wild Mini

Brand: Muzen Audio

Sound: 7/10

Fun Factor: 10/10

Playback time: 8 hours

Bluetooth Version: 5.0

Warranty: 1 year

Price: $109

If you require a very small Bluetooth speaker without a lot of bells and whistles but still want acceptable sound quality, here’s a different Mini to consider…the impossibly adorable Wild Mini by Muzen. Muzen makes a number of different Bluetooth speakers, including one resembling a miniature table radio from the 1950’s. The Wild Mini, on the other hand, is designed with a military style in mind. It indeed looks like it could be standard issue for the US Army, including its hard-sided carry case with retro Sergeant stripes. Too bad Muzen didn’t complete the military theme by offering a Wild Mini camouflage version including a dog tag with the unit’s serial number stamped into it.

A Case To Be Made

In addition to its novel size, the metal housing (the only speaker in my round-up sporting a metal case) and horizontally rotating volume thumb wheel make it stand out from the pack, not to mention a delight to use. I find myself always going for the Wild Mini’s clicking volume wheel instead of my smartphone’s boring volume button. A small plastic wheel on the right provides next and previous track control. There’s even a small, integrated, 3 LED flashlight on top that can be switched between a high or low solid beam and flashing S-O-S like a navy signal lamp. I should also mention the convenient built-in bar allowing the Wild Mini’s owner to clip it to a backpack, belt loop, hang inside a tent, etc. The Wild Mini is dope. If you hang it then I guess you could call it dope on a rope. Sorry.

Don’t Add Water

Muzen’s website states the Wild Mini is rated “IPX5 waterproof” and claims if you accidentally drop yours in the pool you shouldn’t fret. It’s the only model in my Bluetooth roundup with such a rating. IPX5-rated products can withstand sustained low pressure water spray but they’re not waterproof. My Wild Mini has gotten wet but I would never submerge it no matter what Muzen says. I also try to avoid leaving it in strong, direct sunlight for any extended period of time to avoid the zinc alloy metal case from potentially heating up.

Military Bass

Firing up the Wild Mini and playing music via its Bluetooth 5.0 never fails to raise my eyebrows. The sound from this diminutive speaker is clear and crisp, and it will get as loud as a Drill Sergeant (keeping with my military theme). According to Muzen’s specifications, the bass response extends down to 80Hz which is more than I would expect from such a compact speaker, but it certainly isn’t going to cause ripples in your glass of water like an escaped cloned dinosaur would. The Wild Mini would produce a more open sound were it not for its restrictive metal speaker grille. Presumably Muzen felt protecting the 36 mm diminutive diameter driver was more important. It would’ve been even more wild to be able to pair two Wild Minis together for true wireless stereo.

“I find myself always going for the Wild Mini’s clicking volume wheel instead of my smartphone’s boring volume button.”

Original Or Extra Crispy?

As with the other models in this roundup, the Wild Mini has a built-in Li-Ion battery…800mA to be more precise. That will get you about 8 hours of playback time which should more than suffice for most trail hikes and campfire singalongs ( or special ops missions). I should point out there’s a more recent version of the Wild Mini that uses a 1,000mA battery and has a few other new features including a multi-colored light and a wheel in front of the driver that rotates (Muzen calls it a “fidget spinner”). I guess it’s the Wild Mini Wheel of Fortune Edition. Frankly, I consider these “features” a step-down and hardly worth the $50 up-charge. I prefer original recipe over extra crispy.

I can’t resist a Bluetooth speaker in uniform. One look at the Wild Mini and I just knew I had to have one even though I already own more Bluetooth speakers than I need. I guess you could say its appearance is disarming. With its rounded edges and measuring just 3” x 2” x 1”, the Wild Mini is easily the cutest Bluetooth speaker on the planet. Whether you have a proclivity for military-styled things or not, you’ll quickly surrender to it. Getting one means you’ll have to drop and give Muzen 109. No, not 109 pushups, but $109, though I’ve seen it on sale for as low as $90 on Amazon. Should you get one? Sir, yes sir.

Larger than the Wild Mini but smaller than the M90 Mini Blaster is Lofree’s retro-styled Poison. It’s a rather odd name for a portable Bluetooth speaker. Perhaps Lofree named it that because it resembles a giant pill and it’s sound is killer.

Ace Of Bass

Smaller-sized Bluetooth speakers might be cute and convenient, but let’s face it- many of them don’t sound very good. For a plastic speaker measuring 7” x 4” x 2.75” with only 10-watts of power, Poison sounds very good indeed. In fact, it’s the best-sounding speaker in my round-up. Lofree says Poison’s frequency response goes down to 60Hz. No doubt the passive bass radiator that takes up a good portion of its behind is responsible. You can see the woofer in action as the music plays. Baby got back. It’s a good thing Poison has prominent rubber feet to couple it to the surface of whatever it’s playing on, because without them, the speaker would dance all over the place. If I’m looking to impress someone visually, I take out my M90 Mini Blaster or Muzen Wild Mini, but if I’m looking to impress acoustically, I dish out some Poison.

For radio enthusiasts, there’s an FM tuner on board, though reception is so-so and the tiny tuning dial is a challenge for the eyes. Even with my glasses on (which served as the prototype for the Hubble Space Telescope) I couldn’t see what frequency I was tuning. I bought my Poison through a friend in China and its FM dial is lightly back-lighted. Why Lofree left this feature off the US version I have no idea.

The Queen’s English

Some Bluetooth speakers, like the M90 Mini Blaster, use sounds to confirm when the source has been changed. Others, like Poison, use a spoken voice confirmation. The female voice used for Poison’s confirmations speaks with an Asian (Chinese?) accent. The voice Poison uses is pleasant enough but the accent screams “made in China”. It’s a small but important detail. Ordinarily, the manufacturer has the ability to record a different voice instead of whatever comes stock on the Bluetooth chip. A female voice with a British accent would’ve been my choice. A British accent always adds a little sophistication to any occasion.

It’s A Looker

Poison makes just as strong a visual statement as it does with its sound. Retro styling is great, but overdo it and your product risks resembling a cheap plastic toy. In this case, the design is just enough to give it that 50’s retro appearance without making it look goofy or cheap. It’s available in tasteful shiny colors, too, including “Milk Tea”, a kind of very light beige color with just a hint of pink or orange from what I can tell. There’s also a cool chrome dome on the top that changes color depending on the source mode it’s in, though it can be difficult to see the light in bright light conditions.

Make A Wish

On my Poison wish list, I would’ve preferred the top controls and prominent front grille be made of metal instead of plastic. It wouldn’t have added much to the cost and it would’ve given it a more quality look and feel. I also wish Lofree had included an AM band along with the FM, at least for US customers. Alas you can’t have everything.

Poison’s compact size makes it quite comfortable to carry in one hand, though chrome bars are integrated on either side to accommodate a carry strap. My Chinese market version came with a nifty carrying case that resembles a child’s vintage suitcase. Here again, I don’t understand why Muzen failed to include this with the US version.

Li-Ions, Tigers, and Bears, Oh My

Playback-wise, expect about 6 hours from the 2,000mA Li-Ion battery. That’s on the short side but it’s probably due to the bass which tends to be power-hungry. As with most of the speakers in my roundup, Poison doesn’t have a user-replaceable battery. When the battery is exhausted (hopefully not until six or more years from now), shipping the dead unit both ways to its China factory for battery replacement and back again will be costly, assuming the factory will even service it. It will probably cost the same or less to just toss it out and buy a new Poison if they’re still being made then. This isn’t the best solution for the environment or your wallet, but it seems to be the inconvenient truth for many lower-cost portable Bluetooth speakers these days.

“…the design is just enough to give it that 50’s retro appearance without making it look goofy or cheap.”

Poison is priced at $119, not quite half way between the $160 M90 Mini Blaster and $109 Wild Mini, though if you sign up on Lofree’s website, you’ll get emailed a discount code to save a few bucks. By the way, in case you’re wondering, Lofree’s name is a combination of the words “Love” and “Free”. Poison isn’t free, but you’ll love it.

Bumpboxx makes very impressive, full-sized Bluetooth boomboxes sans the cassette deck. I’ve never owned one but I do own their Microboom. Microboom is the smallest and least expensive Bluetooth speaker in my roundup, measuring only 5” x 4” x 2”. It’s a Bluetooth wearable that comes in different shiny colors (including a recently-released, swanky gold-colored version) and includes a 24” stainless steel gold-plated chain to complete the 1980’s image. Bumpboxx also makes a portable Bluetooth speaker that resembles a vintage pager, but I was instantly drawn to the Microboom.

Worth It

Bumpboxx says Microboom “seamlessly blends fashion and technology.” I say Microboom is the bomb, albeit a very basic bomb. There’s no FM tuner, no auxiliary input, and no headphone output, though a Micro SD card input is included on its backside. As with the M90 Mini Blaster, had been the Product Manager for this model, I would’ve left off that input in favor of something more conventional. There are small push button controls on the front for basic functions like power, Bluetooth pairing, track control, volume, and play/pause. The center “display” features a tiny white Bumpboxx logo which illuminates when the unit is powered on. That’s cool, but what would’ve been way cooler is an actual tiny color display that showed artist/song metadata. Of course, that would’ve used more battery power and raised its price, but it so totally would’ve been worth it. Totally.

Go Topless

The Microboom lives up to its name in more ways than one. It’s a micro boombox and it has very little boom despite Bumpboxx managing to shoehorn a passive bass radiator behind the dual 1.2” diameter full range speakers. Wearing the Microboom definitely makes a statement, and it also reduces its bass since the rear woofer’s meager output gets smothered by your clothing. Perhaps Bumpboxx prefers we all go topless. That said, it sounds better than I expected for a 3.7 oz plastic speaker on a chain. One big thing about the little Microboom is it can get fairly loud. It’s only 10 watts max, but this baby boomer(box) goes to 11, and it’ll crank for about 8 hours until its 500mA Li-Ion battery wants a re-charge.

Me and my Microboom.

“…what would’ve been way cooler is an actual tiny color display that showed artist/song metadata.”

Bumpboxx’s website is long on features but short on specs. I couldn’t find out simple details like what version Bluetooth the Microboom used, the frequency response, or even if it was stereo. It took several emails and over a week with their customer support to learn the Microboom uses Bluetooth 5.0. I never got a response to my frequency response or stereo questions, so I used a simple app on my phone to at least verify it’s outputting 2-channel stereo. However, with the speakers being in such close proximity to each other, it’s effectively mono. Perhaps sensing that, Bumpboxx made it possible to pair 2 Microboom’s together for true wireless stereo, with one Microboom being the right channel and the other the left.

You can get your own Microboom on Amazon or from Bumpboxx directly for $99, which strikes me as a bit on the expensive side compared to the prices of the other models I’ve covered in my roundup. Be that as it may, there aren’t many audio devices you can wear that play loud and look wicked cool. Hang a Bumpboxx Microboom around your neck and be prepared to get stopped on the street by impressed strangers wanting to know what it is and where you got it.

Which Version?

You may have noticed the different versions of Bluetooth used by the models in my roundup…5.1, 5.0, and 4.2. What does it mean and why don’t they all use the latest Bluetooth specification? To give a quick comparison, Bluetooth 5.1 and 5.0 include BLE, or Bluetooth Low Energy, which requires less power and thus yields longer playback time than Bluetooth 4.2. Both versions also provide more bandwidth (allows simultaneous connection of 2 different Bluetooth devices) and a much longer range. Bluetooth 5.1 pairs faster than 5.0 and 4.2. However, that doesn’t necessarily mean you should cross out anything on your list that uses older versions like 4.2. The Poison Bluetooth speaker uses Bluetooth version 4.2 and I’ve never experienced an issue using it.

One major drawback to Bluetooth is that Bluetooth IC’s can’t be updated, meaning whatever Bluetooth version your device has is what it will have forever. If a device has Bluetooth 4.2, there’s no way to update it to something more recent. That’s the nature of the beast, and you can bet Bluetooth technology will continue to evolve as it has over the years. So, even if you buy a Bluetooth speaker with the very latest Bluetooth specification (currently 5.2), it’s only the latest until the next version comes along. The good news is devices with older version Bluetooth chips will still work with sources having newer versions. For example, if you own a Bluetooth speaker with Bluetooth version 4.2, but stream your music from a smartphone that has Bluetooth version 5.1, your speaker will still work and sound fine.

I should also like to point out that none of the Bluetooth speakers in my round-up support aptX, a technology that claims to preserve the quality of the music. I don’t consider that a big negative because portable speakers are often used outdoors, which isn’t the ideal environment for audio reproduction. Moreover, in Apple’s wisdom, the iPhone doesn’t support aptX, so at least half of all users wouldn’t be able to take advantage of it anyway.

Juice Me Up

If you do a lot of streaming from your battery-powered smartphone or laptop to your battery-powered Bluetooth speaker, you don’t want your devices running out of power and ruining the vibe. A portable power bank will give your devices a boost when their tanks are nearing empty. Up until recently, most power banks were nondescript devices that sort of resembled those geeky aluminum wallets you see on late-night TV commercials. Enter Shargeek. They designed a portable charger that gets the job done and looks sexy while doing it. I wish I could say that about myself.

The Storm2 boasts a whopping 25,600 mAh of power from its 8 rechargeable, high-density Lithium-ion batteries. It provides four (count ‘em, four) power outputs (USB-C x 2, USB-A x 1, DC x 1) to fast-charge up to 3 devices at once, from phones to drones. It’s also the first portable charger to use a transparent housing exposing the power plant as well as the electronic components mounted on the PCB. Illuminated output jacks would’ve been extra cool, but now I’m really exposing my geeky side. Anyway, you haven’t heard the best part yet. There’s a small, crisp, color display that shows the input/output power, battery pack voltage/current, battery/PCB temperature, charge-discharge cycles, and DC voltage adjustments! OMG. I think I just experienced arrhythmia.

With great power comes great responsibility, and Shargeek takes safety seriously. They’ve built-in protection against short circuits, high voltage, and extreme temperatures. The transparent plastic chassis is fireproof and the Storm2 is rated safe to legally carry onto airplanes should you wish to take yours with you when you travel.

Roughly 3 months ago, Shargeek came out with a new power bank model called Storm2 Slim since it’s approximately 50% smaller than Storm2. It supports 130W high speed power delivery (vs. Storm2’s 100W) and is lighter weight than its big brother, but only includes 1 x USB-C and 1 x USB-A output. An optional, fold-out solar panel keeps the Slim itself charged when electricity isn’t available. Both models retail for $199, though they’re sometimes discounted on Amazon.

We’re all geared up to get outside and enjoy the summer. It feels like it took forever for it to finally get here. Enhance your summer enjoyment even more by bringing your favorite tunes with you. Whether you invest in one or more of the models in my roundup or decide on a different one, know that a portable Bluetooth speaker that makes listening fun in the summer sun is priceless.

Full disclosure: I don’t make a commission if you buy any of the models I recommended. I purchased all of these devices myself and did not receive any free review samples or special discounts. The advantage of this is I can be honest and not feel beholden to any manufacturer. The drawback is it’s a very expensive way of doing reviews!

Trivia: According to Wikipedia, a hands-free mobile headset introduced in 1999 was the first consumer Bluetooth device. The Ericson T39 from 2001 was the first Bluetooth mobile phone. Also launched in 2001 was the IBM ThinkPad A30 which was the first notebook with Bluetoooth.
