The XDM-S710BT, Aiwa's new Bluetooth MP3 player

Aiwa announced a couple of other new flash-based MP3 players (the 128MB XDM-S500 and the 256MB XD-S700), but the one we're really keen on is the XDM-S710BT, a 256MB player with built-in support for Bluetooth. Doesn't look like it'll work with Bluetooth stereo headphones; instead you're supposed to plug your regular wired headphones into it, and then use those along with its built-in mic as a sort of ad hoc wireless cellphone headset so you can make and receive phone calls even while you're walking around listening to music.
