NUU's Splash Extreme Bluetooth Speaker craves sunny skies at the beach or poolside. NUU built this sleek speaker out of aircraft grade aluminum for rugged reliability as well as waterproof protection up to three feet. Don't worry about dropping the Splash in deep water because it floats. As for sound, NUU equipped the Splash with two neodymium drivers and a passive bass radiator for crisp sounds. Bluetooth wireless connectivity adds convenience by connecting to Bluetooth compatible devices as far as 30 feet. The Splash also features a rechargeable battery that lasts as long as 10 hours, and the built in mic lets you take calls straight through the speaker.
