I dropped my headphones and the audio stopped working on the left side, does anybody know how to fix my problem?

I’ve see 80 - 9% success rate in fixing headphones. Very often it’s a break in the cable. This is most commonly at the jack plug end. If this got yanked when you dropped them then it could be that it precipitated a break that was already getting ready to happen. You just have to cut off the old plug and fit a new one. Or it could be a break in the cable on the left side. Assuming they’re cans, not in-ear phones the you should be able to disassemble them without too much trouble.
