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!"
Where's all of the wires?
Shhhh.... they didn't want me to say anything about that but the wires are really not their. It works on the power of your imagination.
Obviously, the wiring is all behind the tv. That is why the sound doesn't work, but the tv does. haha!
