Presenting the Oakley O ROKR PRO:
…the latest in the Sport Performance line of eyewear from Oakley and Motorola. O ROKR™ Pro wirelessly streams digital music, and even lets you control the music wirelessly. Just use the buttons on the frame to select songs on your Bluetooth® Stereo-enabled mobile phone or your iPod® equipped with an ICOMBI™ Bluetooth® adapter. O ROKR™ Pro also offers the convenience of hands-free wireless communication with your compatible mobile phone — which means it works as a Bluetooth® Headset except there’s nothing to clip on your ear, and the conversation comes through crystal clear in both ears.
Apparently this has been on the market since late 2006. Anybody used this in the field?
