Besides being dust, water, and shock-proof, the Big Turtle Shell has a full 360-degree sound, projecting clear audio around 30 feet out, and it can play for 16 hours on a single charge. And since the battery is so huge, you can use it to charge your phone or GoPro a full three to six times in a pinch.
