[Closed] OT: Bluetooth Audio from Sony TV

Hello audio and TV geeks. some help if you please?

I've got a Bravia W8 series TV and i want to connect headphones to it wirelessly. I already have decent headphones so i don't want to get a big expensive docking station type thing.

I already have for my Xperia Z5 the Bluetooth adaptor SBH-20 which works a treat, the supplied buds aren't too shoddy either which for £17 was a bargain. Ideally i'd like something to transmit the sound to my existing BT receiver, but what/how can i use?

I understand you can issues with latency using a 3.5mm jack port, so have seen suggestions about using the L/R out optic type stuff?

thanks in advance.
