I bought these audio extenders via Category 5 adapters so I can connect the projector to a DeWalt radio and use it long distances to have the radio close to me while watching movies can. In the future I will be running a long cable to my surround sound system, but it will do me good to watch movies outside. I don't think the sound will be as good as it was with the short cable, but I didn't notice any change in quality compared to the 5 foot short cable I used previously. They have a 3.5mm jack on one of the adapters and left and right RCA plugs on the other, which worked well for me since my projector has RCA audio outputs and my radio has a 3.5mm auxiliary input. It would be nice if the RCA also had a 3.5mm jack in case you're changing from 3.5mm to 3.5mm connections, but I'm sure you can get an adapter for that if needed be able. If not, you can just buy another set and have 2 of each.* I received this product free of charge for review and my rating is 100% my own honest opinion. Please don't hesitate to ask any questions.
