No wall charger, No AUX input. Once goes flat takes about 4 hours or longer to trickle charge. Lasts about 4-5 hours on full volume (No idea how you could get the 15 hours operational time as advertised, maybe on lowest volume setting) . Sound quality is average. Ill stick with JBL, they are slightly more pricey but they sound way better.

Ive only had the product for three weeks and even when its playing music and charging at the same time, the battery will still go dead within an hour. Its as though it can not charge quick enough compared to what it puts out. Will definitely be contacting the manufacturer and if this is an expectation of the device, Ill be returning it and purchasing something more reliable.

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

Bought this for use at work, for the strength robust features and battery life. Sound quality is great Advertised at 15hrs battery life, mine barely gets 8hrs.

Disappointed that cant get the stereo effect as the app cantvgook up the B 3 to the B 2

Decent sound for the price but the battery doesn't last long at all.

The Ultimate Ears UE Boom 3 is a solid outdoor-friendly speaker that doesn't quite stand out compared with a number of more affordable, more powerful, or more functional alternatives.

Gets fairly loud for its size, IP67 rating, Can be linked to multiple other UE speakers

Relatively weak bass, Few features for the price

A good mix of sound qaultiy/volume and durability

Good overall sound, great volume, great battery life, waterproof

Not the strongest bass, a bit pricey, Not the strongest bass, a bit pricey

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 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
