I didn't try Oratory's settings, but I quite like yours! I just dropped the 4.5kHz peak a little to make distorted guitars less grating. Excellent job! Now I'm curious how this EQ curve stacks up against the one I tuned by ear.

The first image is cable into left input, and the second image is cable into right. These were done on a CRYSound measurement device which are essentially flat plate measurements.

Do you know why they are designed this way?

It's not a massive difference, but I passed a blind test 10/10 times when listening to a kick drum sample and randomly spamming the polarity invert button in my DAW. It's not noticeable on all signals though. Nor is it the kind of difference where I can no longer enjoy music because of the...

Yeah, polarity is definitely matched between drivers at least. Here's another version of the polarity test that I did at home. You can see the MM100 is the only one that dips negative when the positive pulse track is recorded through the headphone via microphone. The monitor speaker and ATH M50X...

Maybe I shouldn't have used the term "incorrect." The polarity may be that way for a reason, in which case it is just negative polarity instead of positive. Not that one is correct and one is incorrect. I tried several other headphones on that same test rig, and they all passed the polarity...

Yep, original post updated. I also have an impulse response of the curve if anyone wants it. The link will expire at some point though. https://we.tl/t-8h7BndNJMy Mid cut: 793.43 Hz, -4.85 dB, Q: 0.342, 24 dB/oct bell Upper mid notch: 2976.6 Hz, -1.44 dB, Q: 1.714, 12 dB/oct bell Upper mid...

This is the curve I'm enjoying on the MM-100s. I've done more complicated versions of this with many bands, but my moves kept trending towards this curve. Note the -6 dB to +6 dB scale, the 24 dB/oct bell shape on the mid cut, and the natural phase setting. I keep failing the blind listening...

So what I'm hearing is people want me to purchase these HD6XX from Drop for $179? Is that what I'm hearing? :eyes: For science? https://drop.com/buy/massdrop-sennheiser-hd6xx

Here are some new measurements. The free air measurement was very close to what I posted here before, so I didn't feel a need to show it again. I think it just confuses people. Here's a slightly different view of the ATH-M50X curve to sorta kinda align with the MM-100 curve.

I noticed the strap popping off for me too. I might just put washers over the screws at my preferred position so the strap stays put.

I just got my second pair of MM-100s after returning my first pair due to some imbalance issue with the right driver. Support did not disclose the issue, but whatever. They may not have checked yet. These do not have any wiring issues and they sound good to me. They take EQ very well too. I...

It doesn't seem to be a connector issue. I think it's a bad solder joint or a shorted strand of wire somewhere. There is a cable that runs from the R ear cup to the L ear cup, and the cable goes into each ear cup where the hinge pins (?) connect to the main ear cup cylinder. I can sort of get...

I guess it is what it is. I don't know if that person likes the LCD-X either. There is no doubt that they sound different though. Unfortunately, I didn't get a whole lot of time to listen to them back to back since my MM-100s right channel connection is misbehaving. Something between the cable...

I had some time with the LCD-X and was able to do another quick measurement comparing to the MM-100. I am not using a model ear or anything like that, so the response curve cannot be compared to a standard test method, unfortunately. Copied and pasted from my measurement on page 75 of this...

Aaaand not even a week later, the connection to the right driver severs as I'm sitting still listening to music. Definitely not the external cable or the player. Time to contact support... *sigh*

Yeah, honestly I have nothing bad to say about the comfort. I had them on for about 4 hours while editing drums yesterday. I can feel the top part of my ear just start to touch the mesh screen, but it's not painful or bothersome at all. Probably due to the gentle clamping force. YMMV

Original post updated!

I took a few more measurements with different equipment. The driver impedance is very flat. I've only ever measured typical moving coil drivers, so it's interesting to see how planar magnetic drivers behave. The impedances are within a 6% tolerance of nominal 18-ohm impedance, and within a 3%...

You're welcome! There was one slightly loose spot on my ear pads that I could pry up a little. I could see the adhesive pulling from the ear cup body, but it didn't look like a strip of tape. I could be wrong. It's hard to see without pulling more than I want to right now.

Here is a quick and dirty measurement using a Sonarworks measurement mic. I played pink noise through each ear cup, one at a time, and I had the headphones suspended in free air away from any surfaces. I moved the microphone around each ear cup, varying X/Y position and depth. These curves are a...

ACTUALLY... Kind of. I have access to a Cry Sound device if I'm remembering the name correctly. It is more of a production line test system, but it does frequency response, phase response, rub and buzz, etc. No averaging of measurements unless I export data and do it manually. I'll certainly...

I got a package today! Unfortunately it only came with headphones, a cable, and no adapter as initially promised. *sigh* I kind of expected it to be missing after reading more on this thread. No time to do a nice setup, so I did an unboxing on the corner of my bed. Lol :dt880smile: UPDATE...

My test for L/R channel routing is the song "Blood on the Ground" by Incubus. Not everyone's cup of tea, but the intro guitar is panned hard right. If it's coming out the left ear cup, something is wrong! :)

I think there's a balance. Yes, they are humans, but they are also a team of humans who specialize in audiophile headphones. All it takes is one person on the team to check a pair and say, "hey, the L and R channels are swapped if I plug into this ear cup. Something isn't right." That is what...
