WOW-SOUND Floating Speaker
Floatable, waterproof, and shaped to fit in a cup holder. The WOW-SOUND speaker is a rugged blaster whose omnidirectional hi-fi sound and 50+ hours of all-weekend battery life are further enhanced by device's ruggedness. It has an IP67 rating that proofs it against water, shocks, and dust.
WOW-SOUND also comes with 360-degree LED lighting for nighttime at the campsite and party time in the pool, plus a perfectly-sized nub on the bottom that allows it both to stand upright on a flat surface, and nestle into the cup holder in your cooler, beach chair, kayak, or inflatable.
