A:Answer Yes, assuming that your TV has a 3.5mm audio output jack, and the cable is only about 6 feet long so you'd need to sit close to the TV.
Note that there are adapters available as I use mine with my XBOX which has a single 2.5mm input jack. These headphones have a boom microphone so there is one 3.5mm jack for voice and one 3.5mm jack for audio.
