There's a part in my earphones where i bit out the cover and today i was biting the "exposed" part again and all of a sudden the sound changed to mono.

How do i fix this? I don't want to buy any new headsets because i don't want to waste my parents' money and disturb them, and i'm saving money for something else.

Also, when i press the part i bit out in a VEEEERY precise angle and VEEEERY precise strenght with my fingers, the sound changes back to stereo for a few seconds, but then it changes to mono again.

Help :(

I'm just searching for help for my own stupidity and my PC doesn't have any sound speakers, so i have to use my headset to have audio on absolutely everything.
