Review on Ultimate Ears Boom 2 Green Machine Wireless Mobile Bluetooth Speaker (Waterproof And Shockproof) (Renewed) by Mark Morrow

Works great and delivers much better volume and sound quality than expected. I play in a dance group and have used this for practice/rehearsals because home sound systems are difficult to use, limited, technically problematic or non-existent. We never know where we're going to practice. The unit provides enough volume for a group rehearsal at just half the volume (iPhone was fully on) in every location we rehearsed. It fits in my dance shoe case! I started taking it on hikes with a hiking friend. We can listen to music when we stop at a remote place for a picnic, without messing around with headphones. When I researched wireless speakers, this was listed in the top ten. In fact, it was voted the best of these ten and lives up to its rating!
