Any time is a good time for an impromptu dance party. Let's face it, you were born with this ability to produce smooth dance moves, so show them off while rocking tunes out of the Outdoor Tech Turtle Shell 2. 0 Wireless Boom Box. The folks at Outdoor Tech kept the same water, shock, and dust proof case that meets rigid IPX 65 standards of excellence, but they made the two speakers and passive bass radiator 30% louder. And you didn't think you could get kicked out of a hotel with a portable Bluetooth 4. 0 enabled wireless speaker! The rechargeable lithium ion battery can run for up to 16 hours, so you can rock it at the crag or on the ski hill and kept the party rolling to the hotel or backyard. Pesky wires always seem to get in the way of your breakdancing routine, but the 2. 0 has a wireless range of 32 feet, so wires or the shell itself won't be getting in your way.
