Anyone here use REW to measure Headphone response?

I'm mixing on a pair of Beyerdynamic DT880 headphones, 32 Ohms. I have Sound ID Reference from Sonarworks and it has a correction profile for the DT880 headphones, 250 Ohms. I'm not convinced the correction curve is quite accurate to my specific pair of headphones. Sonarworks does offer headphone calibration, but since I don't want to ship my headphones to Europe from Los Angeles, and since I'm an REW user, I am thinking of attempting to create my own EQ profile of my headphones. I have plenty of experience with using REW to measure P.A. systems for live events, but I've never used it for headphones.
Does anyone here on the forum have any experience in headphone measurements? I'm not sure how I would go about doing this. I don't think simply setting my calibrated measurement microphone in between the earpieces of the headphones would give accurate results, not in the least because it wouldn't replicate the listening experience of the earpieces being tight against my ears.

if we talk about the accuracy or compliance of measurements with what a person hears in headphones, then this is not the same as measuring great acoustics in a room. Accuracy will not work. Correspondence of measurements to what a person actually hears too. Why? Try sliding the headphones out of place on your head slightly. The sound is immediately different. Not drastically, but different. Therefore, in this case it is necessary to roughly identify troubles, such as large holes in the frequency response, equalize them, and nothing more. I clamp the two halves together with something, and place the microphone between them so that the end of the microphone is in the center. And the microphone must have a calibration file for 90 degrees.

I measured three pairs using a 1/4" piece of closed cell foam, then a 1/4" piece of open cell foam, then a 1/8" piece of felt, all loosely glued together. I pierced a 1/4" hole thru the layers, then poked my UMIK thru about 3/16".

Headphones were measured at about 10 different positions of mic to driver.

Here's the result:

I am not a headphone guy myself... However, I did run across this while recently helping a friend with his headphone kit... You might want to have a look at this open project... It is all about measuring and EQing many, as in hundreds, of headphones... There are several entries that include your Beyerdynamics... See an example here: https://github.com/jaakkopasanen/AutoEq/tree/master/results/oratory1990/harman_over-ear_2018/Beyerdynamic DT 880 250 Ohm (worn earpads)
