The big, bold, beautiful sound of UE ROLL 2 gives adventure a soundtrack. SOUND SO LOUD YOU'LL HAVE TO SHOUT TO BE HEARD. It goes where you go with a stretchy, attachable bungee. All ultra-portable Bluetooth speakers should have one like it-but they don't. You can even attach it to a kayak-it's waterproof. You could ride the kayak over a waterfall in a monsoon with your tunes blasting out. No problem.
