As an example of my point for using a judicious approach above, applying either of the sets of Sennheiser HD8XX measurements and resulting AutoEQ curves from the Crinacle and oratory1990 folders in the Roon DSP system collapses the headstage and tilts the perceived tone of the headphones from relatively full and engaging with a dip in the 2-3 kHz region to thin and hollow, with an overly bright, brittle top end.
Also, these are two sets of measurements of theoretically the same headphones, each with 10 adjustment points, some quite broad, some very narrow. The overall shape of the resulting curve for the same target compensation is similar, but they have some significant differences in the specifics, and they sound different. We have to remember that measurement systems and individual measurement setup can vary quite a bit, so settings from this tool will bake all of that in as well.
As a comparison, based on review of the measured curves in more of a a big picture way, applying a much simpler EQ with a broad 1.5 dB bass lift up to about 100 Hz, another broad lift of about 3 dB around 2 kHz, and a slight drop of about 1 dB centered around 8 kHz brings the bass and vocals up a little but keeps headstage and overall tone intact. Maybe it's this particular DSP implementation, but I would be wary about trying to use any of the precompiled results directly. EQ can have real benefits, but is going to be more personal than automated settings will capture.
