Microphone Problems with Fifine H6 Headphones

Hello, I recently discovered a problem with my microphone from my Fifine H6 headphones. The microphone suddenly stopped working. The computer sees it, I updated the drivers, but the sound is still not recorded. I tried disconnecting and connecting the microphone itself from the headphones to the direct input of the computer, and the sound began to be recorded. If anyone can, tell me what the problem is. Thank you.
