This has got to be one of the best mulit-purpose tools that I own! H2O Audio has a waterproof iPod case that comes with waterproof headphones, and a strap that fits around your waste for use when swimming. Not only are the headphones waterproof but they fit snuggly to the ear so I can wear them under my cycling helmet, or run with them on. You can get the whole set-up (iPod shuffle, waterproof case, headphones and strap) for about 150 bucks!! Its a great piece of equipment for an awesome price.
