Otter oPod

I just got an Otter oPod case for my iPod for Christmas. It is a protective case that is supposed to be waterproof, sand proof, and crush proof. They say it can be used in the gym, pool, hiking, biking, kayaking, and snowsports. I imagined using it for skiing to protect my iPod for getting wet, but if it is fully waterproof and recommended for the pool could you use it wakeboarding? Has anyone used it for this? I have the iPod headphones that are shaped like an earplug and insert into the ear. Can the headphones be used in water or would I need a custom set? It just seems weird that the case could allow you to use the iPod in water. Here is a link to their site if anyone is interested. http://otterbox.com/

I dont think it is water proof. It is coming though for the mini.

iPod mini users:

“OtterBox is designing the fully waterproof oPod mini case to fit the Apple iPod mini and give the same level of iPod protection as our full-size cases. We expect this new line of iPod cases to be available by February 2005”

Yeah with the pool reference though, and in the manual it says it's perfect for swimming, biking, etc. it makes me believe it's water tight. I know water resistant isn't water proof though that's why I'm skeptical. Anyone out there have any experience with this.
