I have been walking around for a few weeks with the sense that my left AirPod was louder than my right one. The difference was minor so I wasn’t entirely sure.
Yesterday the volume in the right AirPod decreased dramatically. It was definitely noticeable now.
I did a quick search which suggested trying them with other devices (same problem) and also checking the balance in iOS via Settings > General > Accessibility > Hearing. Given the issue was across devices, there was no joy there either.
I eventually thought it’s time for new AirPods and started looking at pricing. On the page it mentioned a discussion article describing my exact problem. Somebody recommended I try sucking the AirPod to see if that had any impact (along with a warning that it might also damage them).
Anyway – I was desperate and gave it a go. Turns out it worked perfectly. It was definitely gross as I couldn’t help but think what was coming out of those AirPods. However, they now connect better and sound better too.
