Austrian Audio Hi-X15 - measurements & EQ (Patreon)

I tried making something usable out of this Austrian crap. Holy shit what were those morons responsible for the sound thinking? But it seems to be their "house sound" obviously when looking at the other junk from them, measured by Oratory1990: https://headphonedatabase.com/oratory/headphones?ids=216

On top a measurement with the original tuning (are they all deaf?), below with some EQ adjustments. I used 10 filters, would have needed more to make it sound even smoother, but if you use a Qudelix or other devices with PEQs, 10 bands are usually the limit. It sounds already way way better than the original tuning, which I simply cannot understand, maybe too much Austrian beer damaged their ears. I would be ashamed releasing a product like that. Also a strong imbalance between left and right is noticable which makes equalizing even harder.

Attachments don't seem to work right now, so here the values for EqualizerAPO and I also uploaded a screenshot for Qudelix, which needs slightly adjusted values for a similar result:
