It ain't gonna be that simple, 'cos there are too many unknowns in your question!
Firstly, are your wireless headphones Bluetooth ones or are they the sort where a base unit transmits a radio signal to them?
Next, if your headphones are Bluetooth ones, are you sure that your TV set actually offers a Bluetooth connection? (The exact make and model number, from the back of the set, might help here).
Alternatively, if your headphones are the sort that work with a base unit to transmit a signal, does your TV have a headphone socket?
