There are lots of MP3 players out there - even ones that are waterproof - however, Liquid Force's Liquid Tunes™ waterproof MP3 player ($199.99 and $249.99, www.liquidforce.com) is the first one built specifically for wakeboarding. It's compact and lightweight, and comes with a special Neoprene armband so it will stay on your arm when you're riding. Liquid Tunes is not only waterproof and completely submersible, but it's also shock-resistant and skip-free, even when you fall in the water. It's compatible with MP3 and other common music formats, and even comes with a USB Cable and waterproof earbuds. Choose between the 256 MB and the 513 MB models.
