There’s nothing else like it. The Ultimate Ears’ ROLL 2 is a great gift for RVers who want to be cutting edge with a totally waterproof Bluetooth speaker. In fact, the Roll 2 doesn’t mind being accidentally dropped in the pool, river or ocean, and even comes with its own floatie and bungee cord so it can go wherever you go while your phone stays safe and dry. The palm-sized speaker works via an app, and it’s both USB and AC rechargeable. Can pair with other ROLL 2s for a booming party!
