Samsung writes there is a "Digital Audio Out (Optical)" so that's the only audio output.
Sony documents at https://docs.sony.com/release//MDRRF985RK_EN_FR.pdf tell us it takes in a classic analog signal from RCA or mini jacks.
So you'll need an optical to headphone conversion kit.
Example kit at Amazon: https://www.amazon.com/Sony-MDRRF985RK-Wireless-Headphones-Converter/dp/B00D2BZ1VM
Just the convertor: https://www.amazon.com/DBTech-Digital-Converter-Optical-Headphone/dp/B009AGTC3Q/
Hope this helps.
I have a Samsung model tv UN55KU6290F and I am trying to hookup Sony model MDRRF985RK headphones. Geeks at Best Buy now after selling them to me, say it can not be done. Lee what now take it all back and never hearing the? Thanks JohnB35
