Connect Sennheiser wireless headphones to new LG TV

[terribrow]

I have a new LG TV with no audio output and an old (8 years) LG stereo and I want to connect a pair of Sennheiser wireless headphones (non Bluetooth) that I want to use to listen to my TV. I believe I need a splitter but I'm not sure what kind to buy. Advice please.

if your new tv is wireless turn it on. after it turned on it should connect to the headphone.
