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

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

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

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

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

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

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 60^th 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

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?

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?

Disclosure: I purchased my Sound Burger at an accommodation price, though not in return for this review.

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.

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.

Accessorize

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.

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.

Model: EP203 Poison

Brand: Lofree

Sound: 8/10

Fun Factor: 8/10

Playback time: 6 hours

Bluetooth Version: 4.2

Warranty: 1 year

Price: $119

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.

Model: Microboom

Brand: Bumpboxx

Sound: 5.5/10

Fun Factor: 6.5/10

Playback time: 8 hours

Bluetooth Version: 5.0

Warranty: 1 year

Price: $99

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.

“…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.
