There is an underwater MP3 Player that projects the sound waves directly into your ear bones instead of using headphones.

If you’ve ever been doing laps at the local pool, all the while wishing you had some tunes to listen to, the answer to your problems is here. It’s called the SwiMP3 Waterproof MP3 player. Instead of using headphones, it uses what is called Bone Conduction.

Bone Conduction is what provides the highest quality sound without earbuds. Instead of projecting the sound into your ear like conventional headphones or ear phones, this is placed between the ear and the cheek bone, and projects the sound directly to the ear bones.

This allows clear sound to be heard without interfering with the ears or having to deal with ear buds. It’s also iTunes convertible, so if you’ve got 160 dollars to spend, perhaps it would be a good buy.
