Any time is a good time for an impromptu dance party even in the pool. 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 3. 0 Bluetooth Speaker. The folks at Outdoor Tech put this speaker in a shell that floats in water and equipped it with an IPX7 waterproof construction so you can listen to it underwater if you should feel so inclined. The rechargeable battery can run for up to 25 hours so you can rock it on the ski hill and keep the party rolling to the hot tub afterwards. Pesky wires always seem to get in the way of your break-dancing routine but the 3. 0 has a wireless range of 30 feet so wires or the shell itself won't be getting in your way.
