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!"
You've got to be kidding. Why should anyone invest in this new hardware until the "format war" is settled? Much as I love HD I'm not going to throw away my money until this is settled. It's not like the current DVD SD picture is terrible. It's pretty damn good. Give me a break here.
