Headphone Connection

I have a new LG 50UM6900PAU TV and I am trying to connect my Koss HB500 Wireless Infrared headphones which us a 3.5mm mini jack from the transmitter.. On the back of my tv, I have at my use, Raudio, Lmono, Optical and USB and HDMI. I have tried plugging in using a RCA cable connector from audio and mono to a female 3.5mm which I plug in my male 3.5mm jack but get nothing. I have had LG tell me to try what I already did which they say they don't know if that will work, and also to try optical with an adapter which they have no idea what kind of adapter to suggest. Any suggestions would be greatly appreciated.

The RCA jacks on the TV are inputs to the TV.

So no sound is expected from those RCA jacks.

https://www.lg.com/us/tvs/lg-50um6900pua-4k-uhd-tv notes:
Digital Audio Output (Optical) 1 (rear) which is the only audio output.

There are a lot of caveats about using optical.
1. The TV speakers will go off. Few models let you leave them on and I don't see that option in this model. If there is an option be sure to set the TV audio options to output STEREO or PCM then look around for the options if you want the TV speakers to stay on. AGAIN, few sets do this.

2. The volume control is done by what receives the optical connection. I've lost count of complaints about that.

3. OK, How about #1 at https://www.amazon.com/gp/bestsellers/electronics/3224445011/ref=pd_zg_hrsr_electronics

It looks to be 12 dollars, includes the optical cable and has both headphone minijack and RCA outputs.

Went with #3 and ordered the PROZOR Digital to Analog Converter. Will let you know how it works when it comes in a few days. Thank you in any case.

Good choice.

I see I missed where #1 didn't have the power adapter.

I read on one of the reviews that the buyer powered up by plugging it in the usb port on the back of the tv. That is what I plan on doing too.
