    • Battery life questionable
Color: Ultraviolet Purple Pattern: Speaker
Great sounds, but battery life is questionable. Even when plugged in and charging sometimes it dies. For the most part it's a pretty good product

    • good size + sound quality
Color: Sunset Red Pattern: Speaker
Review Image by Omar Siddique
Nice clear mids & decent bass, in an attractive device, make this an all-around winner. On the negative side: there's a mostly unnecessary app, oversized volume buttons, and a I'd prefer it had a USB-C power connector instead of the old "micro" connector. Over all, this is a great speaker. It also looks really nice, and feels solid in-hand. The UE is small/light enough that I use it as my travel speaker, although I prefer the boom-ier bass on my (heavier) JBL for workout and party music at home. This speaker sounds good, but not obtrusive-- natural for various genres. The default tuning is "fine". Unusual for a Bluetooth speaker, there is an EQ feature on the app, but it doesn't let you turn one band up without decreasing the others. Good for tuning the sound quality for eg, spoken podcasts, but you can't turn up the bass or the treble like you might on a usual sound system. The app also allows using the speaker's top "smart" button to automatically launch playlists without otherwise interacting with a device. A clever idea, but since I usually use an AI (like Google Assistant) I find it unnnecessary, and better to not have too many random apps installed. The speaker works beautifully without the app-- totally optional. I used to buy Logitech PC speakers long ago, and they still make good "gaming" speakers. It's interesting Logi acquired Ultimate Ears, a brand I hadn't heard of before. A good move on their part, as this is one of the two best speakers I tested recently in my search for the perfect hardware. Highly Recommended. ... show more

Review Image by beth80
I bought this speaker cause i heard good thing about it , i get the Boom 3 , my friend told me to get the megaboom, but i get the small one , i was so excited ,i get it one day before my birthday and next day we was going to the beach to celebrate, i put the speaker to charge but i didn't check if really was charging (new product) why to check?.. well next day 2 hours later when the party begins , the speaker died 😢😢 i was really upset all day on my birthday , i had a portable charger and wasn't working, came home put it to charge and nothing , i try other cable , other plug and nothing... I contact Amazon customer service and they replaced for a new one... Today 05/26 put the new speaker to charge and is charging so far , sound beautiful ❤️ but is too early to give them 5 Star ⭐⭐ i will change the start when i am confident that is a really good product ... Updat.. today 03/21/2024 almost two year I get this speaker... I will give them 5 stars cause this radio speaker still perfect, still sound nice and battery life is great.. I bought other one cause u can connect other speaker through the Boom app in the same channel and play music together. 💓💓 It said is waterproof.. well yes it is .. I am really bad and put the speaker inside of my pool 🫣 ofcourse will sound horrible but I took it out and the speaker still good and sounding beautiful 💓💓💓 ... show more

    • Small Speaker, Big Personality 🎶 🔊
Color: Lagoon Blue Pattern: Speaker
I honestly didn’t expect this little guy to sound this good. The bass hits harder than it has any right to for its size, and the sound fills the room like it’s trying to prove something. 😂 The battery life’s solid, the Bluetooth range is great, and it even survived an accidental kitchen-sink splash test (don’t ask). 💦 The buttons are nice and big, so you’re not fumbling around mid-song, and it connects super fast. The best part? It looks sleek enough to sit out on the counter without screaming “tech gadget.” If you want something portable, loud, and just plain fun, this speaker’s a total win. ... show more

    • Great little speaker
Color: Night Black Pattern: Speaker
I've been putting this speaker through its paces for the last few hours and I'm really impressed. Sound quality, water resistance, and build quality is all there. The app is well designed, pairing is quick and easy, and bluetooth range covers my entire apartment. It's important to understand that you're not gonna get crazy sub bass on this thing, but that's not what they're trying to do here. One thing I really have to hand it to UE for on this speaker is instead of trying to reproduce frequencies in those bottom sub ranges, they have obviously set a hard shelf on the EQ that totally eliminates those frequencies from the mix rather than try to make the small speakers in this unit try for it anyway. A lot of other bluetooth speakers I've heard fail pretty hard at that and you end up with distortion and a lot of muddiness in the low range because of it. The tradeoff is that especially low end music (namely drum and bass, dubstep, 808 heavy hip hop and trap, etc) isn't going to exactly shine on this speaker. What does sound great, though, is just about everything else that doesn't rely on sub bass. Rock, jazz, metal, most hip hop, most electronic, funk, r&b, podcasts, etc all sound really clear and have great dynamics. This speaker is also capable of going extremely loud. I couldn't get it past around 70% volume in my apartment without it being excessive, yet the music sounded totally clear and free of distortion even when I cranked it. Also, I brought it in the shower to test and it got wet without issue and dried off quickly. I just got the speaker so time will tell how reliable it is, but count me as impressed. I'm looking forward to taking this on river floats next summer. Really happy that well made, waterproof electronics are readily available now. That was by far one of the biggest selling points to me after the sound quality. They should have used USB C, that's maybe my biggest gripe, I've never cared for micro USB. ... show more

    • So fast on shipping out another one when 1 of 2 didn’t work
Color: Lagoon Blue Pattern: Speaker
I found wonderboom at target on clearance and I should have bought them all. When it wouldn’t take a charge anymore I looked to upgrade. My bf wanted one too because he was so impressed with my old one. So we upgraded to the boom 3, got 2. One was perfect the other didn’t charge. Such easy replacement from Amazon, got it the next day. This one is perfect. You can pair them together to get stereo sound. The sound is phenomenal, pairing is so simple. One of the best speakers out there. I have chosen it over Bose everyday, and I am a Bose girl. If you want immense sound and need it to be easy get any of the wonderboom products. The app is new to me and I need to work with it but I use my Amazon music on it and just party like it’s 1999 in my bathroom getting ready for work. Get the warranty, which I didn’t but should have because when it decides to not charge you will be sad and anxious for a new one. I have had my 1st one for 5 years, I dropped it, regularly and no problems. I use it in the bathroom next to the sink because it is waterproof. The charging dock I haven’t seen it really charge yet, but I could be doing it wrong. But the cord is easy peasy. I love my boom 3 and will stick with Ultimate ears for years to come. You can pair I think up to 20 with the boom 3. I can’t imagine how awesome that will sound. Hope this helps. You will love it. ... show more

    • Love it!
Color: Lagoon Blue Pattern: Speaker
For my purposes, this is perfect! This stays in my car for kayaking, sometimes biking when in a group, party's, golfing, working in the garage......you get it. Things I love: the size, the battery (usb C would have been greatly appreciated!), the controls, yes, it really floats (but the speaker is under water while it does, not really usable in a pool or spa) and it seems to be built VERY solid. The sound is a little better than average, and that's comparing it to my best sounding Sony and a very nice Bose that both stay in or close to the house. I'm not a snob when it comes to portable speakers, great sound is achieved under controlled circumstances with much better equipment, this is good for what it is! The app is nice, but doesn't add a lot for me, I can get most of the functions it provides elsewhere, except for the battery level, nice to check before heading out for a day or weekend. The only small flaw I've found to date is the lack of being able to answer a phone call with it. I'm torn on how important of a feature that really is, but it feels like they could have added it and still kept their minimal, clean, very simple controls in tact. I'm very happy with this speaker and it's sort of become my go-to, it's beating out a number of very nice options! ... show more

Excellent Bluetooth speaker. Great sound, volume, range and durability. I have had mine for over 2 years now. Doesn’t hold a charge as well as it used to, but I am never away from power sources long enough for it to be an issue. I highly recommend the brand.
