This is the Bluetooth speaker that floats while still providing 360° of stereo quality sound. Ideal for the pool, lake, or ocean, its buoyant cabinet is built with an IP67 waterproof and sandproof rating as well as military-grade shockproof technology. Protected within this durable housing, two full-range 5-watt speakers facing back-to-back project high-quality sound in all directions while a rear-firing passive subwoofer generates impressive bass that resonates over the water. Two rings of accent LED lights can be set to pulse to the beat of music, blend slowly/quickly, or remain on a preferred color. Its built-in battery provides up to 11 hours of audio from a full charge using the included USB cable. Also provides caller ID for Apple iOS 10 or higher devices and allows you to synchronize the volume with your phone. 6" H x 4" Diam. (1.5 lbs.)
