I bought this for my Dad so that my Mom could watch television with him at a normal level while he can turn up the volume on the headset as loud as he wants. So far he hasn't been able to use it. He called the number for help that was in the instructions. That rep gave him another number. Then the second rep gave him a third number to call. Then the third rep told him to "go online". My Dad is 74; he does not go online. So Sony has been no help. I live far away, so I can't look at the setup myself. I asked him questions, went online to find answers, asked him more questions. Finally figured out one of the problems is that the cable to connect the unit to his television is too large for the TV's line out, which is where it has to connect in order for both of my parents to hear the TV. Does anyone know if there is an adapter available? I dread calling Sony for this because I don't have all day to be on the phone.
