This is the original cable for SHURE SE215 earphones. It came with a pair I purchased, but I no longer need it after replacing the cable. The color is quite bad. I tried wiping it, but it didn't come off. There's nothing wrong with the feel or smell, so I think it's just discoloration of the material itself. Sound comes out of both the left and right sides without any problems. There are no kinks in the wire or tears in the insulation.
