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!"
Frankly, I'm pretty happy with my HD setup right now... but what I want to know is where I can get the entertainment center pictured on the frontpage of HD101. I have an old tiny Ikea unit and way too many components.
