Apple Earbuds mic don't work on PC?

Try debugging this using different configurations of the hardware.

This to fogure out which part os not working as expected.

See if it’s your Windows config (test the Apple headset on another working Windows system), test your hardware build (again, test the Apple headset on another system), or if it’s the earbuds (test a different headset on the same system with a different 3.5mm plug coaxial speaker-mic).

Could be anythig from the wrong sort of jack to a broken jack to a broken wire in the headset, to an audio software configuration error of some sort.

Is your PC jack 4 part?

Well what parts, especially Mother board did you use? See if you can look up the Audio or ports specs.
