The toughest, best looking, best sounding, waterproof wireless speaker that you will ever have. With a built in power bank (3600 mAh) and the ability to wirelessly connect multiple speakers, you will be able to keep the party going for hours. 20 hours to be exact because that's how long the speaker will keep playing on a full charge. A Loud Waterproof Bluetooth Speaker: Now in its third edition, the Turtle Shell is a whopping 20% louder than its predecessor - which was at least that much louder than the original - and a lot more efficient to boot. It plays louder, for longer, from further away. We've even improved the waterproofing, so you can literally take this waterproof Bluetooth speaker into the water with you. It floats. No lie. Would we lie? No. Design is Important: The Turtle Shell 3.0 saves lives with 360-degree sound from an IPX7 rated polygonal housing that wouldn't look out of place in an interior design magazine - an avant-garde appearance that belies its rugged, dust, shock, and waterproof capabilities. A built-in microphone lets you take and make calls and ask your digital assistant to find out just how deep is the deepest lake in the world (it's Lake Baikal, for the record, at 5,314 feet) while you float off in tubular, tunular bliss. Huge Battery: The upgraded battery capacity of the Turtle Shell 3.0 gives you an outstanding 20 hours of playful playtime, with the ability to act as a portable power bank for your phone or music player as well. If your source isn't Bluetooth-ready, you want to save some battery time, or wires are just your thing, that's cool - the included 3.5-to-3.5mm cable lets you keep listening... but you won't be able to use the impressive 32-foot free-range-chicken mobility that makes the Turtle Shell 3.0 so liberating. True Wireless Pairing: Now that you're free, it's time to get loud. And the Turtle Shell 3.0 is a wireless speaker that can get even louder thanks to its true wireless daisy-chain function - linking up to another Turtle Shell 3.0 up to 15 feet away, to create a wall of well-designed, tougher-than-coffin-nails, louder-than-loud sound that extends a whopping 45 feet away from your source. It's just what they do.
