A waterproof headphone set and a waterproof iPod nano case - cowabunga!

You gotta love people who run into a problem in their daily lives, then go out and create a product that solves it - Pete Dirksing, for example, and the rest of the H2O Audio crew, who created the H2O Audio Series waterproof iPod cases.

These waterproof iPod cases and waterproof headphones (that's waterproof, mind you, not merely water resistant) are submersible up to 10 feet - plenty deep for most casual swimmers, wakeboarders, and kayakers, not to mention hot tubbers and sauna devotees. "I surf with mine all the time," said Dirksing. "We're San Diego surfers, so that's kinda how the product was born."

A waterproof membrane hangs over the headphones' speakers. According to Dirksing, "It's kinda like a one-way door, so sound can get out but water can't get back in." As for the iPod case, "It's a silicone T-seal and a clear polycarbonate case, so it's a similar technology to a waterproof camera housing."

The H2O Audio Series comes in sizes for "pretty much from the third generation forward," and costs $39.95 for the iPod shuffle, $79.95 for the iPod nano, and $89.95 for the iPod video; each includes a neoprene armband that you can use in the water. The headphones are sold separately at $39.95. The company also makes a $39.95 swim belt that you wear on your back, with the iPod on the small of your back so you don't get tangled up in the cords while you're swimming.
