The Big Turtle Shell is a speaker designed for outdoor use thanks to a water-resistant and shock-proof shell. It can also be used as a power bank to charge external devices via USB.
Connection is via Bluetooth 4.0, meaning users can stream music from smartphones, tablets, laptops or other Bluetooth-enabled devices, with a range of up to 30 feet.
The Big Turtle Shell delivers 110 decibels of "clear audio power", its maker claims, and when laid flat sound is dispersed through 360 degrees. A 7800mAh battery gives a claimed 16 hours of playback.
The Outdoor Tech Big Turtle Shell wireless speaker is available now for £200.
