I have to partly disagree with several posts above about the ISK MDH9000: the original ISK MDH9000, as well as all the rebrands/clones of it that I know of
except the Akai 50X), have truly excellent pads. I've owned 2 Marantz MHP-2s + 1 LyxPro HAS-30...same excellent pads--totally comfortable, perfect for the sound, no need to change. I tried changing the pads on the LyxPro HAS-30 (for some obscure reason), and nothing else came close to the stock pads.
For whatever reason, the Akai people recycled that terrific basic headphone design (frame, earcups, headband, wiring)--but used different, inferior pads & screwed up the sound & feel. I'll bet that if you put the pads from my Marantz MPH-2s on an Akai 50X, the 2 headphones would sound and feel indistinguishable from each other...
Here's the ISK MDH9000, complete w/those nice pads (it had been unvavailable to awhile, but it's back):
