One of the people I live with can't help increasing the volume of a certain TV program to a very loud and disturbing level because he can't understand the dialogue otherwise. He watches it with another person who doesn't really need the high volume to understand the dialogue, so I want to know whether or not there is such thing as a pair of wireless or wired earphones that permit the wearer to regulate the volume of TV programs, Movies, etc. to the person's preference while cancelling any other sound in his environment for less interference AND ALSO permit anyone else in the room who's not sporting earphones to listen normally to the TV.
