These are single-sided headphones, so this is the left side which has the cord coming into it. The red, green, and black the green is left channel, the red is the right channel and the copper / black is ground.
As you can see, the wiring for the right side headphone is opposite, where the red and ground wire and connected to the ground and red wire. Why is this? isn't it supposed to be red + red and ground + ground? is this correct how its wired? because my last headphone as far as I remember the red wire connected to the red wire going to the right side phone.
