Can I use an RCA Y-adapter from a STB to connect audio to the TV and to an RCA wireless headphone transmitter?

Question

Recent upgrade to Verizon Fios TV has rendered our RCA wireless headphones useless. Can I use an RCA Y-adapter from the STB to connect audio to the TV and to the wireless headphone transmitter?

Video is using component cable from the STB and audio the red/white RCA plugs attached to the same cable. So the adapters would go on the red and white RCA jacks on the STB to split to two white and two red RCA plugs. One red/white cable pair to the TV the other to the headphone transmitter.

Just wanted to make sure the red/white jacks on the STB are not digital.

Answer 1

You have it exactly right.

Answer 2

2 female to one male gets you only half way there. You will need a 2 female to 1 female stereo adapter to do the trick.
