If you have ever been swimming in a pool that plays music underwater, you know that it is a nice idea but it doesn’t work very well. The sound is muffled and hardly worthwhile. If you are a swimmer who wants to listen to music while you swim, though, hope is not lost. The Finis SwiMP3 is just the answer you are looking for. This waterproof (obviously) unit attaches to the back of your goggle strap. Knowing that even waterproof earbuds would provide distorted sound underwater, Finis found a new solution – bone conduction. Attachments on the side of your face send vibrations through your cheek bones, which vibrate the fluid in your inner ear. This allows you to enjoy sound clarity underwater that you never could before. Bone conduction is completely safe and well-established among the hearing industry.

You can have your own underwater MP3 player now for $200. It features a rechargeable battery and 128MB of memory.
