For a small, portable bluetooth speaker, I think the Boom 3 is a solid, well made speaker with a clear and fairly loud sound. Battery life has been pretty good. I think UE's definition of 'deep bass' might be a bit different from mine. The Boom 3 is understated in the bass but very clear and punchy in the mids and not too thin in the top end. Two of these in stereo sound very nice. The app, however is a bit of disaster and I have found I have to completely power off my ipod everytime I need to re-connect. Sometimes the app won't recognize the device even when it's connected to the ipod/iphone and playing. Also, the Boom 3 fits into a bicycle drink holder/bidon cage. Apart from being a bit light on bass, I've been very pleased with the Boom 3. While it doesn't sound as nice as the Bose Soundlink, it's way cheaper, waterproof and has a much longer battery life.

I’ve tried other brands like Sony for portable speakers but never had any luck as they just kept breaking so I splurged a little and I don’t regret a thing. You get the quality that you pay for and this speaker is incredible. I was worried about having to use the app for everything with this speaker, but you only really need the app for setup and to turn the speaker on from a distance, otherwise it’s self sufficient. Battery lasts a very long time and charging is easy with the added feature of the battery %. Love it.

I bought this today in my favourite colour and tried it out as soon as I got home. On the highest volume, it's so crystal clear. Beautiful sound. Highly recommend this speaker. Worth every dollar

we bought this for our music class it works so well

So good. Had it for a few weeks now. Great anywhere in the house or away on holidays. Don’t have to worry about having it in the bathroom because it’s waterproof.

Whether you’re having a barbecue party by the poolside or out camping in the wilderness, adding your favorite playlist to your outdoor adventure will guarantee more fun. But with the wide selection of portable Bluetooth speakers out on the market today, it can become a bit of a challenge to...

I bought this Beginning of this year, And It has INSANE Durability. It's Been Pegged at walls, And Drowned in a pool for over 24hrs, And there is only a Cracked Case and A Dent in it, The Sound is still loud and Rich.

I was researching speakers for a while until a friend showed me his Boom I was so impressed with the sound I brought this the next day. The only reason I gave 4 stars is the music stops when you receive a call or other app. I've also had an issue trying to rename it, once I did it wouldn't show on my bluetooth and I had to reboot

Good sound... Little better then my five year old sony.. Less then 5 hours from a charge.. Taking back.. Not sure to replace with a mega 3..jbl charge 4 or another sony.. If sony still had an attachment point I wouldn't hesitate

Amazing speaker, well loved by partner this was purchased for. Perfect for taking to the beach or social events. Love the ability of being able to sync up with other speakers.
