Holy crap looks really impressive, just looking at your picture has me kind of excited haha those look impressive! I was reading about and have received recommendations to use the beyer velours but I was afraid going from a pleather type seal to a velour would change the signature.
It is always REALLY hard for me to find closed headphones that seal properly around the bottom of my ear because I have a bonier jaw line without much fat on my neck with a lot of contour I just have a scrawny neck haha
I find the HP100s to be a touch dry and sibilant at times, and it could be due to the change of the pads. Maybe I'll swap them again this weekend and see what differences I can discern. And then maybe I'll buy the Beyer Softskin pads:P.
