Have you tried watching TV with head phones? If I watch TV without head phones, I end up over stimulated and fatigued. I have used both wireless head phones and direct wired head phones. I don't have to strain to understand the voices with the head phones on. If I don't wear them, I get exhausted trying to focus on the words.

Most TV sound systems have a micro-size phone plug similar to the head phone plug on an iPOD. Radio Shack has extension cords and a decent assortment of head phones. I find the head phones with an inline volume switch are the best. Koss sells a few models of good head phones at Radio Shack.

I can not watch High Definition TV. It exhausts me.
