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!"
Oh believe me when i tell you that it is, there is one at my work too and we have it hooked to the same Pioneer Elite 1080p plasma and it looks stunning. However if you are in the market for buying a good one, i recommend waiting until next year as soon has HDMI 1.3 is being used and the players get better and cheaper. Just remember how DVD was when it came out.
