Sound balance issue is still there
So it's 2020 and macOS is still changing the sound balance settings between the left and right earbuds on its own. I found threads from 2013 where people are asking how to fix it. 7 years and still this error is not fixed. Shame. I don't even know whether to ask for a solution because I have a freshly installed system, freshly paired AirPods. The bug is therefore quite deeply rooted in macOS.
And yes, I found an application that keeps the sound centered. It's funny that someone had to create it.
