It helps a little bit; but honestly I wouldn't bother with it on the HE-500 unless you listen to pure 32Hz bass tones.

I'm surprised at how different the D3 looks between the stickers vs no stickers plots (both with open vents) though; do you believe it's just a measurement artifact or are taping the pads down really lowering low frequency distortion in this case?

Better seal / dampening. Air leakage between the flimsy easily deformed plastic ring and the housing of the cup of the stock HFM pads. I mean, you can see the gaps.

That's been my assumption as well since the beginning, heck I only tried this because I knew Audeze does this with their earpads (and coincidentally have ridiculous bass extension), and because I knew the backvents were causing the pads to be propped even further apart from touching the cups.

Did this mod today, I really like the extra transparency this brought:



Basically just a felt disc, with very specific cutouts so that the open portions of the driver are still open, and the magnet/steel portions are covered (by double-sided tape). The intention is to damp away backwaves from the face when wearing the headphones. Subjectively the upper midrange gets a lot "clearer" sounding with this.

I got the idea to do this when I just did the whole foam disc thing on the driver, initially to tame the treble slightly, but it only partially tamed it and ended up sounding tizzy. At the same time though I noticed a completely separate effect - that the midrange sounded clearer and more open - which did not make much sense as I was covering up the drivers with the fabric, but it came to light that it could be reverberation-related, so I arrived at this.

Hey, you stole my idea in progress on my next iteration of Abyss tweaks.

Hehe oops. I promise you I did not think upon your idea at all when I did this mod in one go this morning, not consciously anyway.

Actually, I figured that was going to be your next step since we had been discussing the fazor stuff.

What would be nice is if a handy cutout or cookie stamp (on Creatology foam, etc.) can be made to mass produce the item.

How would this play with the Audeze cans?  The grill over the magnetic structure is much more simple compared to the hifman line.  The new fazor damping/diffusers in the new X line seem to be exactly what this is, but the old LCD2 and LCD3 don't have them.

I'd say a simple printable template would be a good start, just print it on some sort of paper with an adhesive backing, bind it to felt/creat. foam, and cut out the pattern on the felt/foam through the paper. That would definitely be much easier than what I did which was using chalk to roughly mark down where the openings are and then cutting out the openings without any real guidance.
