Its amazing. Great sound, great size for any occasion. Its amazing. Great sound, great size for any occasion.
I have no complaints. My bestie has one of these, just a different model? I got the Motion boom, and she has the Select Pro. Hers lights up too! But? Fine without it. Just for show. The sound is amazing! Loved hers so much, I had to get my own. So worth it. Battery life lasts a good time. Even my 3yo son loves it! HE turns it on when he wants music. So if HE loves it, its a deal! Its lightweight, easy travel and storage. The range? In my home, i can hear it from across the house. Its easy to connect to Bluetooth ( my goofy self was connecting to my besties and it wasn't here, so that was user error, ha!) I love the extra bass it has as well, I love me some bass. The look is simple, but I personally love that. Functions great, again, long battery life, great sound, put it anywhere for amazing sound. Its even better than any of my TVs.

Rich deep base quality sound and loud low price !!! Rich deep base quality sound and loud low price !!!
After my research I was set on buying this speaker, then I saw a picture of the actual size in a room, it seemed small, so I hesitated for about 10 minutes, then decided to buy...soooo glad I did!!! This little speaker is awesome, super clear sound with great deep bass and its pretty damn loud, louder than both of my treblabs together! Super easy to connect and connected fast...haven't had it long enough to speak to the battery life but the sound is everything everyone said so im sure the battery life will be great as well....and the size is actually perfect!!!! Love this speaker, my neighbors are gonna hate it haha and the price point is awesome, incredible value and sound for the price !!!! Get it, you won't regret!!! Put the treblab in the pic for size comparison, don't get me wrong, I love the treblab, its a great little speaker and has served me well for many years, at least 5 to 7 I think, but I lost one and the bass and loudness is just not their so I wanted a new speaker and didn't want to have to sell a kidney to get it and this soundcore by Anker is perfect... bigger but not obnoxious and again, the sound quality is incredible!!! Get it !!!!

Best Bang for the buck
Excellent bang for your buck. I've used this thing from everything to camping to backyard parties. Battery life is great. Sound pounds pretty good, and it fits under the seat of my truck. Thing has taken some abuse too and it stands up awesome. I would recommend this to anyone not looking to spend 5x as much on a JBL. I've had this for a year and a half under abusive use and it's been one of the best bluetooth speakers i've owned

It's loud by default, Which is Really Good!
I love Anger products. I had to get a new Bluetooth speaker because I broke my last one. This is worth the investment! Sound quality, ease of use, appearance, compact, connectivity are awesome.

Bought this instead of the jbl xtreme 3!
If you need a speaker for a vehicle that has no car radio, you'll need at least a 30w speaker that can hold its own bass wise, as vehicle interior size is small, and roadnoise quite often drown out the bass of smaller sized speakers. Initially I had purchased the JBL Extreme 3 speaker, which undeniably sounds much better than this speaker out of the box. However, this speaker has 3 redeeming qualities that made it my preferred device, and 2 additional features that surprised me. 1- most importantly is price. At half the price, and me using the xtreme 3 at work, the repeating question on my mind was "what if this speaker gets stolen, or breaks? Can I really afford to lose a $180-250 speaker like this?". Hence I started looking around for cheaper alternatives, and stumbled on this soundcore anker boom, which has about the same dimensions as the jbl xtreme 3 (fitting perfectly in the dash cubby holder of my company's Mercedes sprinter van). 2- Both the jbl extreme, and the soundcore anker motion boom produce sufficient volume, bass, mids and treble to be used in a car or portable speaker for house parties. I'm probably not convinced they will do for outside (yard) parties by themselves, but that's what surprised me about the motion boom: it has a button to pair it with more speakers, like JBL party mode! Meaning, you can connect 2 speakers together on one device. I didn't know that feature existed on the boom too (it does exist on the boom plus). 3- out of the box, I was a bit disappointed by the boom's sound quality. And while it was easy to add bass with the bass button, soundcore's speaker has an app, that allows me to adjust the eq quite nicely. All of a sudden the boom sound quality was nearing the jbl xtreme 3! I got about 90-98% of the sound quality, for half to 1/3rd the price! 4- The JBL Xtreme 3 has a rated battery life of about 14 hours, but after 8 hours at moderately louder volumes (75%), the battery indicator was at about 1/3rd, indicating me there's less than 12 hours of music, and less each time the battery degrades. The motion boom has a rated battery life closer to 24 hours, but my experience playing at louder volumes is closer to 14 to 18hours, which can span 2 or 3 workdays. Another win for the boom! It's amazing that the boom can be relatively loud (75% volume), and my 5v 1A usb charger can keep up with the charge, meaning, on average this 30W speaker only uses about 5W of continuous power, and closer to 10W continuous at close to max volume. Conclusion: The sound quality was nearing the jbl xtreme 3, and volume wise the boom was actually louder, at nearly 1/3rd the price, and I was able to make the boom less sharp sounding than the xtreme thanks to the built in eq of the app, as well as adjust my sound for different music styles, and save the presets, something jbl doesn't offer in their app. The cheaper price also is less of a loss in case stolen or broken, and the battery life of the boom was better, sounding better in the higher frequencies when playing back lower bitrate (<144kbits) of mp3 files. The boom like most Bluetooth speakers, doesn't play compressed audio natively, so you'll need an intelligent device, like a phone or laptop to hear any sound.

You can’t go wrong with this. You can’t go wrong with this.
This tiny speaker has been such a joy to listen to music with. For context, I am by no means an audiophile, but love listening to music loudly and with a lot of bass. I listen on Spotify, YouTube, and occasionally Apple Music. Here is a detailed review from an avid music listener: Sound quality: This speaker is so crisp and clear it is unbelievable. Even at max volume it doesn’t clip or distort unless the mix on the song is off. The bass is incredible, pretty much the main reason I bought it, for that BOOM. Since the speaker uses 2 passive radiators, to really feel the bass you need to place the speaker by a wall or in the corner of two walls so the sound can bounce off them. It is actually insane how powerful the bass gets when you do that. You can feel parts of your body as well as the floor vibrating. One thing to note, there is a “bass “ button on the speaker and it definitely improves the bass, but look on to the next paragraph to make the bass even better. Out of the box, the speaker doesn’t sound as good as it could. This is because the equalizer has not been adjusted, so the sound signature is pretty flat. If you’re into that then great, but if not you can download the soundcore app and tweak the sound to your liking. In the picture I posted you can find my EQ, and boy does it make the sound louder, the bass bigger, and the songs overall more vibrant and bouncy. I listen to a lot of hip hop, so the bass and low end sounds great with that genre. But I also listen to a lot of indie and folklore, and the highs sound equally nice. Also, for EDM, this speaker is spectacular. The synths are bright and poppy, the drums are commanding and hard hitting, and the singer’s voice sounds great, not muffled or overpowered by the other aspects of the song. (And if they are, you can change the EQ) You can also power off your speaker from your phone app, which is pretty cool. Portability: The speaker is relatively easy to carry around. It has a rubberized handle and is only a couple pounds. I like to put it in my backpack when walking around or hanging out outside. It is waterproof too I believe, so you could get it wet, but I wouldn’t recommend submerging it in the pool because you never really know how waterproof it is until that happens. It is pretty tough too, but it has a hard plastic exterior so it might crack if dropped multiple times. But from my experience with it it’s super tough but easy to carry. Other aspects: The price is completely justifiable, sitting at around $100. It is by far the loudest and clearest speaker you will find in that price range, and can probably compete with $200-300 speakers as well. Battery life is amazing. I can go a whole week, hours a day, at half-volume, listening to music without charging it. And because it’s USB C I can use my Mac or iPad charger to charge it. Bluetooth connectivity is pretty much flawless; I usually connect it to my iPhone, iPad or Mac, and rarely experience a pause or interruption unless I walk very far from the speaker. (Probably 50 feet no walls, or 30 feet with some walls if I had to guess). The only issue I see with this speaker is that it lacks a 3.5mm headphone jack. This could be problematic if your device doesn’t have Bluetooth, but thankfully everything I need to connect the speaker to has Bluetooth. ALSO, forgot to mention that I also watch a lot of YouTube vids with the speaker and there is almost no latency. This means the voices sync up great with characters in the shows you watch, and everything works perfectly for other means of media besides music. Final thoughts: As I said before, I love listening to music out loud, and with a lot of bass. Not just punchy artificial bass, but bass you can feel; deep booming bass. This speaker has that. I literally bought this speaker to replace a full sound system with dual tweeters and dedicated sub because this speaker is more convenient and sounds pretty comparable to the sound system with the right EQ. Obviously it won’t be able to replace the bass from a good subwoofer, but it is more than enough for me and the clarity is actually better than the sound system I replaced. (It is an old altec Lansing system for reference). If you are looking for a more enjoyable listening experience, for basically any genre of music, OR if you are looking to enhance your TV’s sound system (assuming it has Bluetooth), then this is absolutely the speaker for you. The soundcore motion boom makes listening to music more enjoyable and ultimately I’m so glad I bought it. Do yourself a favor and pull the trigger on this one, I really have no complaints about it besides no 3.5mm aux, but it is truly a gem.

Versus Boom+
Got this and the Motion+ at the same time as I could not decide which was right for me based on reviews. Watched a bunch of videos, but still wasn't sure. Hopefully I can make this simple for those in the same boat, the Motion+ audio quality in the highs is definitely better, however lacks bass. So a very load and clear iPhone/iPad style sound which you don't feel as there isn't real bass. If you are using it for movies/podcasts/audiobooks or anything that is primarily speaking and you want to hear what they are saying, get the Plus. If you are listening to music (especially any electronic/hip hop) then the Boom gives you that feeling from the bass that you want. While using the Plus I would never find myself jamming out, it was more of an audiophile experience trying to hear all the higher notes really clear. When I would play the same song on the Boom though, I would jam out and it feels like a lower quality version of my studio monitors. For me being able to bring this camping/boating and jamming out is something I wanted to be able to do, even though listening to podcasts is probably the primary use. The Boom sounds fine with podcasts (not as good as the Plus), but gives you a boombox style sound for music that the Plus can't get close to. And the second you go outside with these speakers, the Plus falls on its face whereas the Boom is thumping and carrying that sound. In the end I went with the Boom because it seemed more well rounded, the plus really feels like it is made for a specific purpose and I don't fit that purpose. If in doubt I would recommend the Boom to anyone, and only if you think it sounds bad, then give the Plus a shot, but for the majority I think they will prefer the Boom. And don't forget you can set custom EQs on these through the app, do some youtube searches and try out some custom EQs, that is what really made the Boom the easy choice for me. So for the Boom itself, build quality is good, this is my 3rd Soundcore/Anker speaker and they are all very durable and well made. The top handle is really sturdy and a great big handle, doesn't feel like I need to be gentle with it which is a plus as I like to travel with it, and knowing it is waterproof is a relief when in the woods. Battery life is ridiculous, I believe their 24 hour claims, typically I use mine for 1.5 hours when I shower/get ready and I have used it weeks without charging. Not sure I will ever be in the situation to fully test the battery, a full weekend of camping was no problem at all. Also love the Bass Boost button on the device so it's not reliant on the app, for podcasts I turn it off and then when I listen to music I turn it on and it works really well with the EQ setup I like. Only downside is hard to call a downside, but that would be size. If you want bigger sound you need a bigger device, so can't knock it for being big. Just be aware of this depending on your uses, if you plan on having it more stationary make sure it will fit.

This Speaker will Change Your Life
I recently got my hands on the this speaker, and let me tell you, it's like having a personal DJ that’s immune to water and bad dance moves! Here’s why I’m convinced this speaker is actually a magical sound genie: The sound is so good, it makes my neighbor’s cat stop mid-meow and listen! Seriously, my music now has more bass than a fish market! When I crank it up, I half-expect my plants to start dancing. They’ve been looking a little droopy lately, but with this speaker, I’m pretty sure they’re about to join a funk band. The rugged design could survive a zombie apocalypse. I'm not saying I plan to test it during a zombie invasion, but if I do, I’ll be jamming out while running for my life! And did I mention it’s waterproof? I accidentally dropped it in the pool while practicing my cannonball, and it just floated back up like, "Is that all you got?" The battery life is so long, I’ve started questioning whether it’s actually a speaker or a time machine. **24 hours** of playtime means I can throw a party and still have enough juice to binge-watch my favorite series afterward. I’ve named it “Energizer Bunny 2.0” because it just keeps going and going. At this rate, I’m convinced it’ll outlast my social battery. This speaker is surprisingly lightweight. I can carry it around like a purse without anyone judging my life choices. Plus, it has a handle! It’s like the Swiss Army knife of speakers—ready for any situation, whether it’s a beach day or an impromptu karaoke night in my living room. The Bluetooth connection is so quick, it practically gives me a high-five when I pair it with my phone. Who needs a relationship when you have this level of connection? And for the times when Bluetooth decides to play hard to get, it has an aux input. Because sometimes, even Bluetooth needs a little break! This is not just a speaker; it’s a lifestyle choice. Whether I’m chilling by the pool, throwing a dance party, or contemplating life choices, this speaker has my back. If you want a speaker that can survive splashes, give you a bass drop that can shake the dust off your old furniture, and make your plants dance, then look no further! Get ready to unleash your inner DJ and make every day a party!
