A friend must use hearing aids to watch television; however, because he is bedridden and watches tv 24/7, I would like to give him headphones that would cancel out the tv speakers while allowing him to hear the audio. To date, he says he always gets a ricochet sound between the hearing aid and the headphone output, which is very disconcerting. Any suggestions?
The problem occurs between the headphone and the hearing aid. There is an echo effect that reverberates every tone. Also, sometimes others in the room want to listen to the audio, so canceling the audio output would not help them. I had not heard of this echo effect before; every Sony headphone set has given excellent sound--but I can hear well.
