Store up to 500 of your favorite songs, and rock out for up to seven hours on one charge with the Oakley Split Thump 2GB Sunglasses. The optics are pretty damn good too. The Split Thump features O Matter frames with UV-blocking Plutonite lenses and Oakley's High Definition Optics for clarity. Pair that with an integrated, wireless 2GB MP3 player that functions with iTunes and a variety of other music players and file formats, and you have a versatile and stylish set of shades for any active occasion. Simple music controls are integrated into the side Oakley icon, and an included USB cable hooks you up to your computer. Remove the headphones when you don't need them, and check your battery level with the three-color indicator light.
