Principle of wire-controlled headphones
Regardless of the interface type (audio interface, USB interface, etc.), wire-controlled headphones basically use four-wire connection. Among them, “shared return line GND” is the common return line of the left and right channels of the earphone, the microphone, and the output control. This principle is certain, but the manufacturer does some tricks on the function of the online pole for monopoly interests. For example, the plug has four electrodes from top to bottom. If the first and third electrodes are reversed, the phenomenon is that one earphone is silent, the line control fails, and the microphone fails; if the third and fourth electrodes are reversed, the phenomenon is: Both headphones are silent. When making changes, just follow the schematic diagram at the micro switch and smooth the wiring.
