Who better to design technology for the pool then Speedo? Most underwater MP3 options consist of cases for an iPod, an awkward, uncomfortable, clunky device for enthusiasts wanting to spend hours in the pool. The Aquabeat, launched this summer ($150), is one the first MP3 players truly designed for underwater use. It even floats.

The one-gig capacity is more than previous attempts, and the design can be attached to standard goggle straps on the back of the head, minimizing drag issues. The headphones hook tightly around the back of the ear, while multiple sizes of ribbed inserts made from thermoplastic elastomer fit nicely into the ear. Developed over a year and tested by top-level swimmers, the headphones promise to stay put during a Phelps-esque flip turn. That's not happening with standard i-buds.
