Left Ear not working, works when I bend the wire a little

I stopped using this headset for a while, so I packed up the wires and put it back in it’s box the way it got shipped to me. I opened it up back in December of 2017 when I got a new PC. It worked fine for a long time, although the wire braid started to wrap around itself, causing the underwire to become exposed (not the actual wires under the entire thing, just the not braided point that has a matte color, it’s still covering the actual wires) and bent at a very steep angle. This was completely harmless to the audio quality for months. Eventually, sometime back in August, the left ear stopped working suddenly, and if I bent the wire in a certain position it would start working again, until the wire was touched again. I dealt with this for the longest time until suddenly it just stopped working no matter how much I bent it and what direction I bent it in. These knots happen all up and down the wire. I’ve been fine with this for a long time, and eventually I got used to it, but honestly its the most annoying thing. I paid 100 bucks for these headsets, and they had the best sound quality I had heard in a long time, and I desperately miss the amazing sound quality. I honestly don’t have the money to pay for these again. Any help is appreciated! Thanks!
