It is probably much more basic than yours, and it is definitely not definite: (but definitely good enough atm, lol, awaiting perhaps new ear cushions)
B1 G+3.0 F70 Q0.7 shelf
B2 G-3.0 F1.14k Q1.4
B3 G-1.5 F2.7k Q3.0
B4 G-1.5 F8.0k Q5.0 (necessary? Q5.0 is maximum Q here)
B5 G+2.5 F1.40k Q0.7 shelf
Bass button G0.0 F80 Q0.7 shelf (to check if I’m missing out on bass, had “G+3.0 F30” but didn’t seem to do much)
Treble button G-2.5 F10.0k Q0.7 shelf (cannot go above F10.0k or below F3.0k on this button)
Tried “B5” G+5.0 / G5.5, but couldn’t get them to be comfortable on many songs. Too much piercing highs and sibilance.
Filters adjusted by ear mostly (from your/original tables). My hearing doesn’t go much beyond 12.5kHz, so ymmv.
From a decade long experience in audio (with speaker/subwoofer setups) I remember that only small EQ adjustments work, besides filtering out resonances. So boosting a “null” is a futile exercise.
