The headphones that fit the headphone connection will work. Commonly, it's a 3.5mm plug or the big version, 6.35 mm. It's called a TRS connector: http://en.wikipedia.org/wiki/TRS_connector
But some models of TV, regrettably, don't have anything to plug it in. Then you can't use headphones.
I remember a member who only noted that after he had bought the TV. Obviously, his selection criteria had been incomplete!
