Tech-Life BeatBlock - Wireless Bluetooth Speaker: Rechargeable, Ultra-Durable and Splashproof (Bombproof Rubber Exterior-Black)
I wasn't really expecting this to work for me, even though all the reviews said it was tops.  I took it out of the package, charged it immediately, turned on my bluetooth on my phone, selected the speakers...then BINGO!  It works, even when I walked into other rooms!  Great sound!  I LOVE IT!  Buying 3 more now for other family members!
