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 have to disagree with how this post is worded. Changing the picture settings is definetly not calibration. Calibration involves adjusting a myriad of settings in the service menu using expensive equipment to tune your tv to the environment it is in. All the regular picture controls do change but getting an ISF calibration is a whole other story. Not to mention that manufacturers often use different components to make the same model number of TV. My service menu settings differ from other models based on which components are in my model so taking some generic settings for any of these models is just asking for a crappy picture.
