Since you mentioned you got your hearing checked and everything is okay… Auditory Processing Disorder is a pretty common neurodivergence with a lot of overlap with ADHD/OCD/depression/anxiety/et al. It’s common with any or all of the others, but it shows up in neurotypical people too.

I’m ADHD and have APD as well :)

My building has these and 2 of them failed in the first year. Can’t replace the battery so had to replace the whole thing.

I don’t fly a lot, but that’s also its main use. I’m on a trip right now, I bought Pokemon just for this trip :)
