SamuelS Posted
Great brand I had the boom 1 for about 8 years till I popped a speaker base sounded cracked. Upgraded to this one and clarity and sound is amazing for the price.

Great value and true 360!
BRANDON Posted
Really happy with this purchase! One of the only true 360 portable speakers with great sounds. Some of the others seemed to have more bass but this one is best for hanging out with a group of friends.

Great item, but upgrade if in loud areas
Strprod Posted
Pros: Phenomenal battery life, extremely portable, easy to use, decent sound. Cons: Volume. Works great if sitting around a campfire or table, but on a boat we could not hear it. Just know you need something louder based on the environment. For hanging around, it works great.

Great small speaker
BenJ Posted
Great little speaker that pairs great with bigger UE speakers. Particularly adds tons of sound when used with the UE Hyperboom, but also good portable speaker

To purchase or not the ue boom
BrianB Posted
Tested out all the portable speakers for a gift to my daughter's ended up picking this one for the crisp sound and wonderful black Friday week deal. It was a no brainer once I heard it perform and saw the price. My daughter just loves her speaker and tells everyone about it.

Really like this speaker.
Diane Posted
Thus works for music as well as being read to. This is loud enough for me to hear over the shower and will even go louder. It doesn’t get fuzzy or distorted when it is loud. It does everything I want it for.
