Dunno if someone experienced this, my KL sounded more harsh starting this week, vocals started to feel shouty. I’m sure it’s not my ears as I tested my other IEM and they were indeed sounded the same as I perceived and even a loaned B2Dusk felt less shouty/sharp.
I changed cables, tip rolled and nothing worked to get that harsh/shouty feeling disappear. I’m starting to feel that it might be a broken driver but couldn’t confirm.
