Oakley Thump 2

Oakley has been in the sunglasses business for years, mostly catering to the needs of athletes who need gear that works with them as they work up a sweat. The brand stepped into the realm of technology when it introduced its MP3 sunglasses range, which includes the Thump 2 model. Besides providing UV protection, the shades offer 1GB of storage without any troublesome wires getting in the way. One charge supplies up to six hours of playing time, and in case you lose track of time, the glasses have an indicator to display battery life, so that you know when to recharge without breaking your stride.
