I am going to have my Grandfather staying with me for at least two months. he is deaf as a post ! In his own house he either wears headphones or has the vol. full up ( lucky neighbours ) when watching TV. My question is : is there a way of listening to the TV through headphones without cutting the sound from the TV, so that i can watch it as normal and he can have his headphones full blast ? any suggestions would be appreciated by my Grandfather, Neighbours, and Me !
