Why carry a pair of polarized sunglasses and your MP3 player when you can sport the Oakley Split Thump 1GB Polarized Sunglasses? Store up to 250 tunes on the integrated music player, and control your tracks with the hidden controls integrated into the Oakley icon. Rock out for up to seven hours on a single charge. Remove the headphones when you dont need them, and sync up the MP3 player with iTunes or a variety of music players and file formats with the included USB cable. The lightweight O Matter frames feature Plutonite polarized lenses for UV and glare blockage, and Oakleys High Definition Optics provide the utmost clarity.
