After some more time with the headphones, I find this chart I found closest to what I hear with a few differences. It appears this is compensated for the reviewers own ears?

They definitely need that little mid bass hump brought back in. I also find them a bit lacking in the lower mids, so a 300hz broad peak filters helps fix that otherwise I find them to sound thin. The 2.5khz peak annoys me for sure. The 10khz peak super annoys me but is easily knocked down. I also found reducing 1khz can help take vocals out of the head so to speak, and more in their own space. I would adjust to taste. I do not feel the 4khz range needs brought up at all despite the dip in the graph. I have also reduced 6khz a bit as it felt a tad harsh.
I required a little extra bass, and I feel if one tackles all those issues above with EQ, the headphone is amazing. The 2.5khz and 10khz peaks make the biggest difference to me, without them taken care of the headphone is kind of harsh.
I am pleased with the headphone, while not exactly the "needs no EQ" I was hoping for, I don't know if that even exists in the closed world. I will say the headphone responds very predictably and favorably to EQ. Some headphones do not, as the closer the get to neutrality, the more the unfixable flaws are revealed such as a DT770's mid range null. The price is easy to eat when one remembers nearly every other closed headphone is worse than this. One can spend more than double on a Dan Clark pair and still need EQ. It is what it is.
