Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
I work at P.C. Richards and Son, and in my system we are due to get this player 12/12/06. Warning though our system sucks, and is never right, and usually takes longer so this thing wont be out for at least another 8 months, lol. Sony corp. the new Microsoft.... sad.
