Replaced an old cable, which wasn't as good quality. It had recently stopped working in stereo. This cable works in stereo and sound seems a little clearer and the cable is nicer and doesn't catch on rug or chair like the old one made of plastic.
As anticipated, this cable does what it's supposed to. However, my intention in buying this cable was to use it with the Modern Retro headphones (which do not have a detachable cable) to make the end plug thin enough to fit through my phone case. The ordinary male-to-male Onyx cables are thin enough to fit through, but these are not. Disappointed, as I do not see any other solutions to this issue aside from using a different set of headphones.
Silver: standard male-to-male Onyx cable.
Black: This male-to-female Onyx cable.
