Right AirPod sound not very loud

So I did both, suck on the main speaker grill and used a little 70% ethanol to clean out the dirt (ear wax). I was care full of wiping the ethanol quickly with a dry q-tip (which I also used to apply the ethanol). I held the AirPod downwards to prevent alcohol from going inside. I also lightly blew into the AirPod and then alternated back and forth. There seemed to be some blockage as the more I did it the more air filtered through to indicate there was obstruction due to dirt. Amazingly the AirPods are back to their original loudness. My right one was the worst but now just as loud as the left and both are louder.

Take heed of the post on "at your own risk". You might actually damage the internals by the sucking method and using 70% ethanol. My AirPods were well beyond warranty and my initial support call with Apple was not very useful as they said I was not under coverage anymore and I should replace the earpiece at $80/each. Could buy a new pair for that price.

If your AirPods are under warranty I would take to apple store first. If not, the sucking method seems to work but may not work for everyone.

FYI, I used to wear my AirPods while running. I'm sure the sweat and ear wax built up over time and clogged up the earpieces. I've read some more online and seems that the AirPods may not be suited for full workouts where you sweat more than usual. Other than that they are great. Now that I have full loudness I'm happy. I might go back to wearing them for running now that I have an unofficial method of cleaning. Hoping the new AirPods with improved sweat proofing and with wireless charging are announced soon.
