    Got all of Dekoni's HD6XX pads in for a comparison. Baseline is against my modded HD580 (red/orange line). For those who are wondering, I'd say it's basically a slightly brighter-sounding HD650. You can find instructions on how to mod your own in my thread in the modding section.

    All of the pads were measured with the following condition: stock HD580 w/ foam piece in the back (I re-inserted the foam piece for this comparison), absolutely nothing sitting in the front (so bare driver exposed). Why nothing in the front? You'll find out soon.

    Modded HD580 vs stock HD580 w/ Dekoni Velour ear pads:
    [​IMG]

    Quick sound impression: dark.

    Modded HD580 vs stock HD580 w/ Dekoni Leather ear pads:
    [​IMG]

    Quick sound impression: decent, kinda dark but still neutral-ish.

    Modded HD580 vs stock HD580 w/ Dekoni Hybrid ear pads:
    [​IMG]

    Quick sound impression: very dark but kinda shouty as well.

    Modded HD580 vs stock HD580 w/ Dekoni Fenestrated ear pads:
    [​IMG]

    Quick sound impression: decent, not dark, kinda smooth but sharp-ish sounding.

    I like leather and fenestrated the most. Leather is a bit more shouty than my mod, but it sounds very similar overall. Warm-ish tilt. Fenestrated is a bit of an interesting beast: it's a dark/smooth sound but it has a weird sharpening effect. I'm guessing this is because bass is not as crazy, and treble is fairly linear (in measurements at least), plus there really is nothing sitting on top of the driver this time so it has a bit of that "raw" sound. Would have been interesting if this was an HD600, because I get the feeling the HD600 would be almost neutral here.

    Anyway, I don't think any of the ear pads above will play well with HD650/HD6XX, sadly. They may be interesting on HD58X and HD660S, though, and I'm guessing Dekoni did their testing on those headphones (or one of the new HD600) rather than on the HD6XX.

    Trivial: all of the pads are very well-constructed. My old Senn ear pads are close to the end of their lives now and they look very sad. Will order new pads, which come with the stock foam piece, and then I'll do another set of measurements of these pads versus the stock headphone. Right now, these pads sit at over 2x the distance from driver compared to my poor ol' Senn pads.

    Will do photos/pics later when I'm less lazy and it's no longer night time. :)

    My HD 600s do not sound as good as they used to and I believe the pads have a lot to do with it. It's nice to know these Dekoni's might play well with them

    Nice job!, @Bill-P

    Looking at Dekoni's blog, they seemed to develop and test for hd600: https://dekoniaudio.com/frequency-response-curve-new-dekoni-sennheiser-hd600-pads/

    [​IMG]

    Above is their measurement on fenestrated pad with hd600.

    I had very little trust on their measurements, because I suspected conflict of interest lol.
    But at least their results look somewhat consistent with yours.

    I got significantly more bass with the Dekoni pads, but this was with HD650.

    Could be a pad seal issue? The Dekoni pads have a flat top where the rounded stock foam will conform better.

    I still want to see what the Dekoni HD800 pads do. Quick measurements on Dekoni's rig showed an almost completely eliminated 6kHz peak.

    I thought Marverino measured the Dekoni HD800 maxipads and they didn't look promising. I was also considering picking up some HD800s on the cheap when I saw the Dekoni-published measurements, but it doesn't look meant to be after all.

    Same here. WAY too much bass with bleed into the mids. I thought that they were just bad with 650.

    Bah, so the scrunchy velour Senn pads remain the best-sounding option for the HD650? Darn!

    The HM5 pads are bassier than stock but not nearly as much so as the Dekoni.

    Yeah, these pads seem to be boosting the lows enough that I don't think there should be any front damping on HD580/600. This would probably mean HD650 will have mega bass with these. Especially if there is no rear damping.

    ______________________________________

    Anyway, with the Dekoni fenestrated pads and some readjustments to the rear damping scheme (not just foam piece anymore), I was able to arrive at this:

    [​IMG]

    With no front damping. That's pretty good. It eliminated the bass hump of stock pads. I'm thinking the same tweaks to HD600 will be very very interesting.

    Edit: in case it was hard to see what changed versus just having Fenestrated + stock foam piece:

    [​IMG]

    Red = Fenestrated + rear damping tweak
    Blue = Fenestrated + stock foam

    Basically: less bass hump, slightly less warm, lifted upper mid (3KHz to 5KHz) by 1dB, and lifted 8KHz by 3dB. Overall less dark/smoothed over.

    Comfort-wise, stock pads are still more comfy and less sweaty. My ears get hot with the fenestrated pads.

    Will take some photos and post instructions on how to do rear damping later.

    Thought I might add a brief data point here. Received a pair of fenestrated sheepskin pads today and have been running them on the HD600. @Bill-P's intuition seems borne out by my experience. The net effect of the pads leaves the inherent neutrality (imho) of the HD600 intact. There's an impression of a slight boost in the bass, although I'm not sure "boost" is the precise term. The bass seems weightier, like it has more heft. It seems to hit harder. Overall the signature of the HD600 is thickened. The headphone still sounds forward but is vaguely more polite. No sense of a weird sharpening effect, or an increase in shoutyness. Subject to change, of course, but the fenestrated sheepskin pads might be good for people who find the signature of HD600 a bit thin-sounding. I'll probably leave them on.

    I haven't a feel yet for how the fenestrated sheepskin pads affect the technicalities of the HD600. I'll just say they don't seem to harm resolution or clarity. I should note that I find them more comfortable than the stock pads.

    NB: Most of my listening has been done with the foam left in. The brief impressions here http://www.superbestaudiofriends.org/index.php?threads/source-av-meet-impressions.5748/#post-189887 describe the HD600 w/ fenestrated sheepskin pads and the foam removed. I listened briefly with the foam removed and, at least so far, have preferred it left in. I'll experiment more with that variable.

    New here :) First post...I just got my Mod House HD600 adaptors & installed my pleather HM5 pads. I expected the results to be bad based on other people’s impressions. I initially bought the HM5 pads for my M50x trying anything to make those cans sound decent, nope! made them way worse. So I had the pads laying around. Figured I try them on my HD600s. Haven’t listened much but I noticed a little more umph in the bass & a little fuller sound which I liked. Going to do more A/B listening to get my thoughts together but so far not bad.
