If your smart TV has an "audio out" 3.5mm connection (looks like a black square with one hole in centre; just "audio out" not "digital audio out") and your headphones use RCA connectors (the red and white round old-fashioned ones like a stereo uses) you can just go to any electronics store and get a "3.5mm to RCA" cable/adaptor. I needed male to male but the store I went to only sold 3.5mm male to RCA female, so I also got a pair of RCA "plug couplers" (barrel connectors) that are female-to-female. Total cost: $20. Voila.
Okay CNet land, I have been staring at this set of wireless headphones and my father's brand new LG LM6200 Smart TV for the past hour and cannot come up with a solution. My father likes to fall asleep to the TV, though his girlfriend occasionally can't take it. I bought these headphones so that they could both be happy.
I bought for him the Sennheiser RS120 wireless headphones. His TV, as mentioned above, is the LG LM6200.
I have tried all three "channels" on the RS120 receiver, as well as "external speaker," none of it worked. I would really like to make these things work as they cost a fair amount!
Any help would be greatly appreciated, thank you
