Lighter more perspiration resistant and improved with interchangeable lenses. Crank the tunes.

Music matters when you're grinding through a two-hour workout four times a week but there are few things more annoying than a headphone cord that drags against your neck or slaps against your back. Oakley cuts the cord with the integrated MP3 music player in these Thump Pro Sunglasses. Unlike previous Thump eyewear this new incarnation is lighter and features interchangeable lenses that you can switch out to match the weather. Because athletes tend to prefer Thump eyewear for cycling running skiing and snowboarding Oakley refined the design to be far more perspiration and even moderately weather resistant. In some respects the Oakley Thump Pro resembles the popular Oakley XLJ eyewear but the wider O Matter ear frame contains a compact solid state NAND flash memory that comes in three sizes (256 MB 512 MB and 1 GB created to store roughly 60 120 or 240 songs respectively). The 75Mhz DSP acoustic speakers that move in six directions for fit giving you audio bliss in 18-bit Sigma Delta DAC fidelity. Whether you're listening to the music or waiting for the next track the Plutonite lenses consistently block 100% of all UVA UVB UVC and all blue light glare with Oakley's patented XYZ Optics® for clarity that extends along the peripheral edges of the lenses. The Oakley Thump comes complete with a high-speed USB cable for quick tune transfer between your PC or Mac computers. Battery life runs about six hours.
