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!"
Good call by #1...I have friends that are convinced that just because tvs say they support 1080i/p theyre actually going to display in that resolution, when most of the stuff they are looking at is actually only 1024x768 and will have to downgrade 1080 sources to 720p.
