The Good:-Great 360 degree sound quality from jazz to hip hop (video shows range of music)-Easy set up-Stylish design and small footprint so incredibly portable-Really does float (tested that by throwing it into the bathtub!)-Drop proof (dropped it from 3 feet and no issues)-Battery lasted 12 hours on LOUD volume-iOS app is well designed and works great with the speaker-Firmware upgradable

Amazin sound, great design and really loooong battery life

Setup is easy, the app is very well designed and easy to use.

Lastly the iOS app is very well designed and makes it easy to adjust the equalizer on the speaker

I really enjoyed the single Ultimate Ears Boom speaker I used on its own for about two years, but after experiencing the disaster which is Party Up mode and the Ultimate Ears Boom app, I will never again purchase another Ultimate Ears product

First, the Ultimate Ears Boom app is a huge frustration

Listening to an entire song without missing parts is impossible when using the Ultimate Ears Boom speakers together in Party Up or Two-Up mode

Superb audio, easy to use, excellent battery life + outstanding craftsmanship equals awesomeness!!

The app enables additional features and I recommend it.

New features add flexibility and ease of use.

When used as a single speaker, the Ultimate Ears Boom 3 speaker works well

Nice balanced sound, a little light on the bass as you'd expect from such a small speaker.

Sure, not as deep as a bigger & heavier speaker, but good for well balanced sound.

- The "user interface" is really really nice: I love the fact that you only need to press the On button once, quickly, and it starts up

I guess I am a relic as I think the heavy bass makes for a less than neutral speaker and can actually kind of ruin the listening experience

The JBL Xtreme has great bass, but is slightly more expensive, is larger and (while portable) is much heavier.

Provides excellent bass and a full rich sound even at higher volume levels

Over the years I've had a whole lot of Bluetooth speakers, many of them with better bass, different features than this one

Bass is limited by speaker size but is adequate.
