How to change the left and right sound of headphones

An easier way is to remove the earphone shell from the incoming line. There are usually five cables in the main cable, and the thicker cable wrapped with white rubber is ignored. The other three are bare wires wrapped with enameled wires. The main line of a normal earphone will have three different colors: red, copper, green or blue, which respectively represent:

Red right channel anode,

Copper-male negative electrode,

Green or blue-left channel

There are two ways to change the left and right channels: after you disassemble the ear shell on the incoming side of the earphone, you will see that two wires of the main line are connected with another thin wire, one of which is the wire just mentioned (thicker) and the other leads to another speaker. Just switch the red line or blue line on the main line and connect them (for example, the blue line is welded to the speaker and the red line is connected to the other one), so the method is: weld the red line. ) Switch between left and right channels.
