I use them to control the volume from the TV to the headphones. In particular, I use a slider to "decrease" the volume coming from the TV ("fixed audio"). Volume and sound quality are good. But the build quality is questionable. The "strain relief" on both ends is very weak and I know they will eventually give way to internal wiring. Also, plastic-coated wire is very thin and fragile. UPDATE: July 2020 (2 -> 4 stars). ) More than 6 months later and after some "roughness" I'm surprised at how good they feel. I would give this product 5 stars but the "stress boots" could use more plastic. Update: December 2020 The device has still held up despite some abuse.
