I have a few measurements now and can provide a preset, but the positioning sensitivity on this design is fairly high, so please make sure your ear is sitting towards the rear of the ear cup/the headphone is pushed forward and low on your head. If not, this likely won’t sound very good.
Hell, even with this preset it probably won’t sound that much better.
I have to say, this is a design I think is fundamentally flawed in numerous ways, and if you have this headphone I earnestly recommend trying to return it and buying something more normal. This preset won’t match the “target” precisely, because the unit I have on hand sounds bad if I don’t go quite a bit further with the upper midrange cuts. So keep that in mind; you will need to adjust manually above 2 kHz or so.

Good luck, and please please make your own adjustments in the treble above 2 kHz and bass. It is necessary.
Red, blue, and gold lines all show peak filters centered at 500 Hz, +6 dB gain, with varying Q factors. The red line is for Q=1, the blue line is for Q=2, and the gold line is for Q=5.
So, as you can see, higher Q provides a narrower peak and lower Q provides a broader peak. Q doesn’t change the height (gain) just the range of frequencies influenced.
Ha ha! Thanks for the cautions. I’m not convinced Harman is an appropriate target for these, I just want to experiment. I think EQing them is going to be a challenge as they seem to be sensitive to both individual HRTF and placement.
Sure I can see doing that if this was my only headphone. But since I own a few better choices if I want to maximize, say, timbre or detail, I’m going to keep these for their unique staging.
Looking forward to a Headphones.com review, even if it is negative.
