When connecting headphones to the TV with newer devices dedicated socket of the TV is muted. One can only hear through the headphones, an additional person therefore has no TV sound. That is also plug in the back of the TV with difficulty. This adapter I can put in the Scrat port where he stays, eliminates the problems just mentioned. I just have a Scrat port on TV. About a multiple plug I run the RCA adapter and rated here an external receiver. By the changeover switch to the RCA adapter I received with my wireless headphones to the TV sound and the receiver tone. Unfortunately I have to resort to conversion also behind the TV, that is with me but relatively easy. Another simple alternative without expensive additional equipment I have not found, so full purchase recommendation!
