Some of it has to do with the audio equipment too.
Like I can hear the difference on my high quality headphones when connected to a decent USB audio interface device or my Denon home theater system with Technic speakers. Barely, while a difference is there. But can’t tell on my gaming headset or PC speakers.
And my ears are messed up. Had two sets of ear tubes when I was a kid and have some scar tissue on my eardrums which resonates with odd frequencies sometimes.
