Airpods Gen 3 very quiet

I purchased my first pair of AirPods Gen 3 about 2 years ago and a few months in they started to have audio issues on the left AirPod to the point where the sound was so quiet I could only hear audio when it was at full volume and I was in a quiet room. I took it into the istore and luckily it was under warranty and they replaced both AirPods. I am now onto my second pair and both sides are having the same problems as the last pair I got and now I only use one as the other side is too quiet, and the side that I do use only works at full volume. I tried to take them into the istore again to bring up the same problem and the only thing they could do for me was quote me on a replacement which is not included in the warranty and will cost the same amount as purchasing a new pair.

Is this a common problem in these versions of the airpods or am i just very unlucky? And does anyone know a solution to this?
