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!"
Not to be critical towards sony's pr team, but that has to mathematically be the worst place of a tv I've ever seen. Tons of light, no curtains, and a couch with it's back to the tv - made out of bricks (in case you get any fancy ideas about turning it around to enjoy your new bravia).
