Note how the HD800 mods get rid of the resonance even on the v2 coupler.
PANASONIC WM 61A CALIBRATION FILE UPDATE
Will update this post when I remember again.ĮDIT 2: Also attached CSDs in sexy white (36db range). I know that I forgot something, I just can't think of what it was. I just find this to be the better compromise (between too dead and too reflective). You could also make the argument that this material is not reflective enough and doesn't show resonances between the side of the head and the earcup properly and to a degree this is correct. I can't say for sure as I've never had the chance to measure one. The catch is that this material will probably not seal with the STAX headphones, so the bass measurements will probably be inaccurate for stats. With my open headphones, HD600 and especially HD800 the bass measurements actually more closely match what I hear and are very close to the bass measurements my mic-in-the-ear-canal measurement method gives me. This is mainly supposed to be a more easy to use Marv-V1-type coupler, without having to use a solid plate for bass measurements.

That I got it for free was simply a bonus. Maybe this is part of the secret (that it technically isn't one material, but multiple materials in one). I think this is essentially multiple dense open cell foams squashed together. (more close up pic, so you can better see the structure of the material - looks to be open cell foam) I ended up using the following material (about 3cm thick): This is why I then decided to build a coupler closer to V1. Most headphones will measure better on the V2 type coupler than the HD800. I still didn't like the results this coupler gave me, at least for the HD800. When I used a V2-type coupler I used a thicker piece of felt (I think it is 3mm), roughly the shape of my ear, to absorb reflections. I already said that I don't like the creatology foam as a coupling material: I feel that it gives too much of a seal (Marv used a piece of felt to deliberately break the seal) and is too reflective somehow.

I also measured the loopback (DAC->amp -> ADC) and the impulse response changes a lot when changing windows audio settings (my output is always at 44.1kHz, I only changed the input sample rate). When I look at the impulse response I usually look at -0.5ms to 3ms (slightly longer range), though -0.5ms to 2ms makes a lot of sense for the better headphones out there.
