H2O Audio's Waterproof Housing for iPod nano is one of the very best-built iPod nano cases we’ve seen.It is slim, small, and allows you to dive into the Artic without your iPod getting all water-y.This case is one of the more expensive at $80 and includes a neoprene arm-band. The optional waterproof headphones sell for an additional $40.Unlike any of the other nano cases on the market, H2O’s design is an impressively elaborate clear underwater housing for the iPod nano that provides full access to its screen, controls, and headphone port while it’s protected at up to 10-foot depths, or from common rain, splashes, or snow conditions when enjoying outdoor sports.

A mechanical Click Wheel cover that enables users to continue to use the nano’s controls even in deep warm or cold water - a feat that’s not as easy to accomplish as just placing a thin plastic or rubber cover on top.The case also has a LatchTight locking system and SealTight connector that’s compatible with standard 3.5mm headphone plugs. It works perfectly with the nano’s controls, and the rest of the case is basically pinpoint-level perfect in its alignment with the nano’s components, and not as easy to scratch as one would expect from clear plastic.Once-included waterproof headphones are now sold separately.
