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!"
This is the first time I have looked at a release date for either new format and said, "I would love to have every one of those titles". In fact, it hasn't even been close. This is the first time I have seen a list with more than one title on it that I wanted. I haven't bought either format's player yet, but this may get me started...
