I know it's typically used for aux/sound settings but these cables are also used for split keyboards. That's why I bought them to connect both sides of the split keyboard. And since my setup was black and red, I wanted a black or red wire. The signal is excellent and the cable is long enough that I could place the two sides of the keyboard on my desk if I wanted - or use the cable. Cable tie or velcro to keep it neat and in place. It would be a little more useful if the 3.5mm plugs were right angles, but at this price point and with this kind of functionality I can't complain at all.
