Problems with jack input on MacBook Pro 2015 15"

When i plug apple Earpods into the jack input of my MacBook they work only as headphones, mic doesn't work! I've tested them with another MacBook - they work, everything is ok. Why there is this problem and how i can try to solve it? Thanks!
Best, Marco

Mmm… as long as the headphone plug and cable are not damaged, then the issue is within the logic board socket assembly. Apple uses its own design so you’ll need to find a junker with a good socket. Replacing the logic board is the very last option.

As to what went wrong there are two switches within the socket which the signals from the internal speaker/mic to the external ones. Here’s a deeper write up Understanding Audio Jack Switches and Schematics.

Sometimes you can use a toothpick to re-align the blades if twisted, I haven’t found this works in this series but worth a try

I think you might want to find a USB DAC unit which will by-pass the socket issue. Or just use a Bluetooth headphones/buds.
