Thanks for your words. I tamed down the treble this evening putting cheap foam tips bought from aliexpress. Treble went down hard and it's now a bit more pleasant, but i feel i miss now the detail i had. So i'm gonna try some tip rolling tomorrow as i have like 20 different tips from many other headphones. Atm i wanna try without EQing as my DAP is cheap and only has pre-set EQs.
