Underwater Audio specializes in waterproof audio solutions. They provided a sample of their Swimbuds Sport waterproof earbuds and a waterproof iPod Shuffle for review. Both products performed well during extended underwater use. Waterproof headphones have several advantages - users can listen to music while swimming or exercising without worrying about damaging their device, they can connect to any Bluetooth-enabled device, and they allow listening in the rain or when it's wet outside. Waterproof headphones are also cable-free, providing freedom of movement without wires catching or tangling.
