Oakley Thump PRO MP3 Integrated Sunglasses

The Thump PRO sunglasses are a new and improved version of the Thump 2. Oakley refined the sport design into a rimless, sleek, more lightweight frame, with the added durability of sweat resistance and features Unobtanium� components that actually increase grip with perspiration. With High Definition Optics (HDO), you can't get better clarity and the convenience of interchangeble lenses are available so you can optimize vision for any sport environment. THUMP PRO combines three decades of Oakley optical innovation with the convenience and performance of cutting-edge audio. This isn�t just a state-of-the-art song player or a world-class optical instrument. This is a training tool that brings out the athlete in you. Its crystal clear sound bathes the brain in music that lets you endure the burn and take your training to the next level.Note: Songs transferred to iTunes from CDs are in the .m4a file format, which is compatible with THUMP PRO. Songs purchased from the iTunes Music Store are in the .m4p format and are not compatible with THUMP PRO because Apple� reserves that format for iPod� use only.
