In other news, I am more than well aware of the principle that BAs don’t burn in, but I’m puzzled - when I first put these into my ears with the black filters, the treble was so sharp it serrated my eardrums, crazily large amounts of harsh sibilance... moving to today, I can use the green (treble) filters and no sibilance to be found, I know of brain burn in, but that first impression can’t have been that wrong, I’m quite sure.
Why are you using the treble filters in the first place if you thought they were treble-hot with the black?
