Comments about Sony Sony 900Mhz Analog Wireless FM Frequency Stereo Headphones, 150' Effective Distance.:
The ear phones worked as planed out of the box. My wife uses them to listen to TV while I read. Because of the RF system, she can walk away and still hear the TV, even in the next room. They get a little uncomfortable over a long time, but it's tolerable. The audio quality is excellent. Typical Sony.
