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!"
900 lumens, WHO CARES. Unless you're in a pitch black room it's no good. Even in a pitch black room that's not that good. I have a 2200 lumen projector and I still wish I had more lumens. Great contrast ratio though.
