    Experimenting with silicone ears. They're not quite as soft as my ears and slightly smaller, but that's just nitpicking. They are soft and ear sized.

    The main problem right now: I realized that you can't get good measurements like this without a good middle ear simulation, which won't be easy.
    Multiple volumes with the right damping. The B&K 5128 (4620 ear) uses at least 3 from what I can tell, maybe more. I don't want to just attach an aliexpress IEC711 coupler - that would be too easy. I actually want to make my own and the idea is to be able to fit larger microphones.

    Even without attaching them to a head (I do have a head here, just haven't made a hole for the silicone ears, yet) the FR curves I get from measuring speakers look promising and they mostly work for compensating the headphone measurements.

    This will take a while, but I want to make my own dummy head/HATS. I want it to be slightly more damped than the current solutions since those seem to be more resonant than real heads:

    The 5128 does seem to be the most accurate between 100Hz and 5kHz, which I would categorize as the most important range, but doesn't seal as well and also has sharper resonances.

    It could take forever to get it to where I want it to be. However here are some WIP compensated measurements of my modded HD600 and modded HD800. I think there should be a bit more ear gain, but I do have to admit that the HD800 is still lacking in upper midrange energy, despite the mods.
