Hello!
Headphone * * * two wires, divided into four conductive cores, as follows:
1. Two copper wires are the ground wires of headphones, commonly known as negative electrodes.
2. The red core is the right channel of the earphone (usually the red core is the right channel, but some manufacturers connect the red core to the left channel).
3. The blue line is the left channel of the earphone (usually the blue line is the left channel, but some manufacturers will connect the blue line to the right channel).
See the figure below for the connection of earphone cable:
