Can you plug in headphones into audio jacks on the side of your tv?

If there is a 3.5mm jack socket on the television, it is almost certain to be a headphone output. Other connectors such as RCA (phono) connectors are not intended for headphone use.
It's always worth checking the manual first, just to be sure.
