H2O Audio iPod case
If you're an extreme sports fanatic, these waterproof headphones and iPod/iPhone cases from H2O Audio could be just what you need

Calling all extreme sports fans. Whether you're into a bit of surfing, kayaking or plain old-fashioned swimming, you need never be without your iPhone or iPod again thanks to a range of new waterproof headphones and armband cases from H2O Audio.

The Surge headphones and Amphibx armbands are guaranteed to keep your iPod, iPhone or MP3 player nice and dry up to a depth of 3.6 metres.

They've been developed in comjunction with top athletes Laird Hamilton and Natalie Coughlin, who were part of the USA swimming team at this summer's Beijing Olympics.

The Amphibx armband's shape and materials have been chosen to comfortably grip your arm while you're dropping in, cutting it back or wiping out. The locking system provides a water-tight seal, and the clear touch window enables full operation of the iPod Touch/iPhone and iPod click-wheel control.
