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!"
The company that makes those speakers went out of business a few years ago, and I actually forgot the name. I am really happy with them.
All my equipment -- including my Blu-ray player -- are in my closet. I have long run cables run from the main closet to every HDTV in my house.
