These are such bad pads, avoid these if you cherish your HD800/S, Elite Hybrids are just bass killers that also mute the highs and overall ruin the soundstage, imaging, and just about everything. Oh, and they're hot as hell, so you may need a personal fan blowing at your face to offset things.
I assume the PC37X would work with the PC363D headphones.
I just bought a highly needed 'official' replacement set, which are slightly firmer and less comfortable than the originals, but 'ok'.
I'm not sure if these are worth getting for yet another replacement. They seem like the red-dead stepchild in the deal, only offering "choice leather", not four options. From reviews, it's not clear they'd even be as comfortable.
NooborghiniWhich headset? I only own the Hybrids for the HD800SDR mod. All i can say is.. stick with the stock pads. One of the secrets of the HD800 is the ear being positioned within the driver 'chamber' it gives you that sound depth and impact. With these Dekoni pads, because they're so padded, it removes your ear from that sweet spot and the sound becomes thin and distant, not to mention no bass response at all.
Not sure about the HD700 or PC37X, but Stick with stock when it comes to the HD800
