My roommate has this speaker, and we use it to play music in our room all the time. It’s wireless and completely waterproof, so you can use it in the shower or on a boat. I think that it’s very practical and quite attractive as far as speakers go. The plus and minus signs control the volume, and it can get very loud. The quality of the sound is very good considering how small the speaker is. A cursory Amazon search revealed that UE is one of the more expensive waterproof speaker brands, but I’m definitely a fan.
