one side of headphones arent working

[Snookk]

hello humans so i have these headphones that if i plug them in my pc only one of the sides gives audio
but if i plug it in my phone or laptop it gives audio from both of the sides

The headphone jack is probably damaged on the PC. Wiggle the cord, both channels may work if it's in just the right position.
