This looks so cool! It is not out in the market yet, but soon it will be! Both Sunglasses and MP3 player at the same time. Orders will begin to ship on 2005-06-15. Now you don't have to be bothered with wires and loose connections. The lenses are Flip-up lenses with contours to protect against sun, wind and side impact. The glasses are available in 256MB and 512MB versions. Needless to say, they are not cheap!
