I'm a heavy AirPods-user, probably using them for 6–10 hours daily. Currently, my left AirPod has gradually, but also quite dramatically, lost its volume capacity over the course of a couple of weeks.
It would be vital for you to know, that this is not the first time this has happened. I have been an AirPods owner for about 1.5 years, but during that time this problem has occurred with both my Left and Right AirPods multiple times at different occasions. I have been able to get replacement units from Apple as the decreases in volume has been significant. I believe my current Left AirPod is the fourth unit I've owned which exhibits this problem.
I need to pan the audio in the system to achieve a rough L–R equilibrium. Currently, I need to pan the volume 50% Left from the Middle, which indicates a 50% volume loss.
While the deterioration has been slightly gradual, it is also dramatic, and has happened rather suddenly. In fact, two times (with different units) the volume capacity has gone jumped from unnoticeable to about 20% loss and then almost 50% loss over the course of a week or two. This would suggest to me that it's not due to earwax buildup, but something technical, but I'm not sure.
I have tried the AirPods on multiple systems, so I know it's something relating to the unit and not the OS. I have tried cleaning them quite routinely, even by following this suggestion to suck on it 🤢to remove potentially clogging earwax from the behind the membrane. Unfortunately it doesn't seem to help.
Does anyone know what the problem can be, and how to fix it? If it's likely due to dirt, is there a sure-fire effective way to clean them? For equipment at this price, it doesn't feel satisfactory that they lose significant volume over time.
