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!"
"PS, when playing halo 2 on my 360 if there is too much action on the screen my framerate will drop noticeably. Anybody else have that?"
Can't say I've noticed, but it wouldn't suprise me. Emulation is a very resouorce intensive task. Take a game that was pushing the Xbox to it's limits, then run that in an emulator - you're bound to have frame rate issues. The fix? Halo 3! I'm anticipating that game more than I really should. So much of my life has been lost to Halo 2 that I should really hope for no Halo 3. It's a sickness.
