This is interesting: Blueserker noticed a pulled listing on Amazon for a Nike-branded 1.5GB MP3 player with Bluetooth Headphones, manufactured by Philips. It looks like it will (would be?) powered by a CF hard drive and would sport (get it? Nike?) a rubberized finish. Since Nike-branded MP3 players tend to be more sports oriented (at least in theory), wireless headphones would be a great accessory, as catching your headphone cord with an errant flail and ripping them off your ears is one of the least fun aspects of exercising with music.
