Underwater Audio took the Apple iPod shuffle and waterproofed it. The fourth-generation, 2-GB shuffle brings the luxury of personal music libraries to the ears of swimmers. Instead of a soundtrack of splashing arms and kicking feet, swimmers can receive motivation from the latest dubstep mash up or Taylor Swift ballade. Sealed from the inside out, water does not stand a chance at seeping through the cracks. Attach it to a suit or cap with the clip provided and enjoy long battery life that equals hours of music. This device does not include waterproof headphones. But, not to worry, the next summer gadget on the list has got it covered.
