i understand that "burning in" is a myth
and that even if it is true (which i believe) it is more relevant with dynamic drivers.
but why are people talking about how a lot of custom iems sound like crap at first but get better within 200 hours?
they're the same balance armature as a lot of other iems that don't recieve benefits from burning in.
does it have to do with the hard acryllic material or something?
