Head Acoustics, dunno what model, I'd guess a precursor of this: https://www.head-acoustics.com/products/artificial-head-binaural-recording/hms-ii3 . Have you asked at Headphones.com?

BTW I have an archive collection of HeadRoom measurements if you're looking for something in particular.

@Biodegraded would love to peruse if you don't mind! Just trying to triangulate some VERY old impressions I wrote of my first "nice" headphones a while ago against how they measured, since I genuinely had no context for them at the time. HD428s, haha.

Will PM you. If Tyll used the same HATS (which I think he did), it was the Head Acoustics HMS II.3 - scroll down to 'A side note about ...' here: https://www.stereophile.com/content/innerfidelity-headphone-measurements-explained , and also look at the HeadFi page linked from there.

A worthy project would be to digitize Tyll's graphs and then run analysis to normalize to other comps using average of select dozen headphones.

@purr1n didn't @Serious do something quite similar a few years ago with a custom compensation too?

@Bill-P doesn't seem to be around anymore, but he had all the raw data (spreadsheets).

Here are the .pdf files, my own "compensated" files and some other stuff from his site: https://drive.google.com/drive/folders/1SjExAs5SPWop6Q_Gk6m-grXdI48aVGR5?usp=sharing

EDIT: woops, wrong folder

@Serious nice! Requested access to the files.

Got a couple audio related folders in one folder and I clicked the wrong one. Added you to the right one.
I don't think I ever finished digitizing all the plots, but there are .txt files compatible with REW with my compensated graphs for many of the graphs IIRC, which should be interesting for @purr1n aswell.
