A set of two Turtle Shell 3.0 Bluetooth Speakers lets you create true wireless stereo sound.

Real stereo: Wirelessly connect two speakers together using Bluetooth v4.2. It's really easy. First you pair one speaker with your device (phone, tablet, computer, etc.) then you pair that speaker with another Turtle Shell 3.0. You can have the first speaker up to 30' from your device and the second speaker up to 15' from the first speaker.

Waterproof, buoyant housing: The Turtle Shell blasts 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.

Up to 20 hours of operating time: The upgraded 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.

Wired input: Included 3.5-to-3.5mm cable lets you keep listening, in case your source isn't Bluetooth-ready

Controls: Volume up or down, Skip track forward or backward, Pause or play track, Answer or hang up call, Pair with devices, Power on or off.
