The equalizer, which is graphic, not parametric, and only 8 bands, can be slightly corrected. That is, the highs are simply in full minus (and there is a range of +/- 6db), low ones are almost in full minus, medium ones are in full plus, well, the transitions are somewhere in the middle for smoothness. In short, I attached the EQ settings. But the poisonousness at high levels is still not completely removed, and this is noticeable even to me with very elderly ears.
