"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!"
Suddenly, I want to kick Comcast SportsNet Bay Area hard for leaving the FSN brand. I want more Sharks games in HD, dangit!
I miss FSN too. I want my MLB on FOX theme to pump me up during the Giants games! You know what I'm talking about, dun dun dun dun dun dun dun dun, DUN DUN DUN DUN DUN DUN! The CSN music sounds like it comes from a low budget high school sports program.
