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 have been expecting this for several years now. It will be good when I can come home from a day at the beach and put my BT camera down on the coffee table and just by connecting the two (TV and camera) I can show my wife the fun me and the kids had... and have my BT phone sitting with me while I am watching heroes and when a call comes through the TV auto asks if I want to take it or not. Stuff like that. technology is soooo behind what we need and want. sheesh.
