I think my headset is a HyperX Cloud Alpha. I bought it for over 100€ about a year ago. After only two days, the left side stopped working, but then it somehow started working again. Unfortunately, the problem came back yesterday and I can only hear from the right side now. I'm fed up with it. I opened the left earcups to check the wiring, but I can't see anything wrong (I don't know much about electronics). Can a pro please help me? I don't have the money to buy a new one
