Tech-Life BeatBlock - Wireless Bluetooth Speaker: Rechargeable, Ultra-Durable and Splashproof (Bombproof Rubber Exterior-Black)
2 minutes from box to broadcast. Easy setup, Awesome sound! Battery last a long time, and you can still use BeatBlock when its charging. The only downside I've found is that my microwave interrupts the signal.<br />I haven't used any other Bluetooth speakers, so can't make comparisons, but I'm extremely satisfied with my BeatBlock purchase!
