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!"
I think CIH setups are too much work. They're great when you can get content that pairs up well with it, but some stuff you're better off not using through an anamorphic projector.
In a CIH home setup, you move the anamorphic lens out of the way when watching 1.33:1 or 1.85:1 material.
