A friend of mine wants to use his Shure IEMs on a treadmill to hear the audio from his faraway TV. Does anyone know of a system enabling him to wirelessly transmit the TV audio to a small portable receiver or something that he can keep on his person or attach to the treadmill and plug his IEMs into? The receiver would have to be battery-powered, because he can't have it plugged into a wall socket while he's on the treadmill. I think he's willing to spend a couple hundred dollars for this capability. I looked around a little and was surprised not to find anything. Thanks for any ideas!
