The genuine leather version of these pads have been best aftermarket ones that I've found. I use them on my D2k and my X00 PH. They have a similar effect on the frequency response as the old J$ leather pads. I little extra bass (add some attenuation rings to really boost it and get +10db bass over stock for some basshead fun, lol), a bit less shout in the midrange, all without boosting the treble. No, not the same sound as stock, but I prefer the change, personally as it's more in line with what I thought they would sound like based on people's descriptions. Additionally, they are
much more comfortable and won't flake after a few years.
