Powered by H2O Audio technology, the X-1 Interval 4G Waterproof Headphone System features a waterproof case with integrated headphones designed for the 4th-generation iPod shuffle. The Interval is the only waterproof iPod case designed just for swimmers--finally swimmers can have the same advantage of training with music that dry land athletes have enjoyed for years.
Developed for Swimmers
Integrated goggle loops make it easy to attach and remove the case from almost any swim goggle. Short headphone wires make it convenient to contain your personal soundsystem entirely on your head, keeping your arms free of wires.
Easy to use, the Interval features push buttons that align with the iPod button controls for playback and volume control in the water or out.
Each package includes 5 sets of Elastomer earplugs (XS-XL) to ensure a waterproof seal and comfortable fit while swimming, running, and working out.
X-1's patented waterproof technology allows the case and headphones to withstand heavy perspiration, and submersion to 12 feet (3.6m) underwater for an unlimited amount of time. Because they're waterproof, they simply rinse clean as needed.
The headphone's ergonomic sheared shape sits flush with the ear and is designed to promote proper alignment of the earbud with the ear canal for superior sound and less drag, in or out of the water.
Improved Bass Amplified Sound
The latest waterproof technology delivers improved bass quality, while sound-isolating, watertight earplugs provide warm sound and dynamic bass response powered by waterproof 8mm neodymium drivers.
