These were done by a user at Headfi - not exactly a professional but he has some equipment for it - I have the MM-100 myself and like them so far.
EDIT: These must be off as M50x doesn't measure like that so I deleted the graph

The M50X measures nothing like that so the MM100 measurement says nothing.
Pretty much what I've been thinking after doing some advanced googling. Thank you

I would kindly suggest you edit your post to remove the graph, I wouldn't usually say that but in this case it is so poorly done as to be completely misleading. No judgement on you, thank you for sharing what you initially thought was useful.

Makes sense as it's the most important region to get right when mixing.

Thanks. Yeah, I'm not a huge measurements guy, but that graph looked nonsensical -- especially the huge peak in the mids.
Hey everyone, I'm coming from the Head-Fi forums. I see many people didn't appreciate my measurement method! Understandable - It was a quick/repeatable way for me to see the relative driver response compared to the ATH-M50X driver response. It was not meant to be an absolute frequency response using standardized measurement methods. (The 200-measurement average part is pretty fast. It was an FFT average with pink noise in Room EQ Wizard - not sine sweep after sine sweep. Haha)
I see how people could find my measurements misleading if my disclaimers were not taken into consideration.
THIS is a sine sweep measurement on a CrySound device that is meant for headphone production line testing. Again, it's likely not going to produce the same measurements as a calibrated GRAS/AP system, so I can't say if it's any more useful than the comparative pink noise test I did. Can anyone confirm if planar magnetic driver polarity is typically negative? That seems odd to me.
The flat-plate measurement thing sounds interesting. Wouldn't that be just as useless as a free air measurement without having some baseline reference of how most flat plate measurements look though? It seems to be adding in more variables whereas I saw the free air measurement as a way to remove as many variables as possible.
What is the typical flat plate mic depth? Flush with the plate surface? What about angle of the mic? What about the plate material's acoustic properties? What about the clamping force of the headphones? These are genuine questions so I could make something that will be useful to people.
Here are links to my original measurement posts for context.

You have what is takes to be a "satisfied Audeze customer" :D Just kidding The note saying "Available in several months" is probably just an expression of the distributor's frustration. I still hope to test the MM-100 before Christmas :) The distributor here in Norway still has Oct. 6...

@ squibble: Thanks for showing us your frequency plot. Interesting! I would like to eventually have real leather pads on mine and wonder if the stock pleather pads - imported from the Far East according to Sankar in the video above here - are glued on with two-sided tape like the LCD pads...

His comments were a little harsh, but he made some good points. If the gel-filled protein leather earpads cost more than real leather and are actually higher quality than real leather, why wouldn’t they be used on their flagship model? Why wouldn’t they be used on all of their higher end...

Well, I forged ahead anyway. I had to send my previous Audeze MM-100s back to Audeze. There was some issue with the right driver intermittently dropping out.
I got the replacement pair today and tried the flat-plate measurement.
Maybe these measurements will be more useful to people. The free-air measurement matched my last pair very closely, and the new pair sounds similar to the old pair from what I can remember. Consistent manufacturing is nice!
The image above is referenced to 1kHz. It's kind of hard to compare though, since so much more of the ATH-M50X curve is above the MM-100s. The one below is compensated a bit so the curves are matched at 1.6kHz. It's arbitrary, but I wanted to see the ATH-M50X curve dance around the MM-100 curve where possible.

Would you happen have any other headphone references to compare to MM-100 measurements maybe? HD600 or 6XX?Well, I forged ahead anyway. I had to send my previous Audeze MM-100s back to Audeze. There was some issue with the right driver intermittently dropping out.

Please send your new pair to Amir!

Looks like a typical Audeze.
One driver being faulty already is a bad omen though.

May I have at least a week with a functioning pair?! LolPlease send your new pair to Amir!
I'd love to see proper measurements of these! I tried some of Tyll's 30/300Hz square wave tests too, but it's hard to hold a mic, a block of foam, and headphones all at once. Maybe I'll rig something up at some point.
Yeah, that was a bummer. It seemed like a wire wasn't making full contact, or maybe there was an intermittent short somewhere. I could kind of squeeze the hinges on the ear cup and change the signal volume in that ear cup. Hopefully this pair doesn't crap out on me either, because I was sitting very still when the first pair got cranky.
I only have HD280 Pros or HD380 Pros at my disposal, but the studio I'm going to this weekend has a pair of LCD-X and HD650S. I think I saw some Beyerdynamic DT something-or-others there too if that's of interest.

It is like a much more affordable LCD5 that is mid centric. But Audeze drivers are very welcoming to EQ.

As long as they are good for EQing (minimal resonances and low distortion) then they are good enough for me.
I tried some EQing today, and found the headphones to take the curve quite well! It's not too crazy with resonances, so a wide 4-6 dB dip in the mids plus some tiny 2 dB cuts here and there made them really pleasing to listen to.
Speaking of low distortion, I can't even get a proper distortion reading because the noise floor in my environment is too high. My hunch is that the THD is low enough.
