I've been stumbling across this forum and google, but couldn't really find the solution for this.
Considering DT770 / 880, but they're circum size.
 
I don't know about other series, but how about DT 440, 331, sennheiser HD560, or Ultrasone's velour? Are they matches with ESW9? Portable.
 
My HD25-1 fits perfectly, but the ear hole is too small, causing the sound gets muffled bad.
 
Please advise 
Thank you..

Very unlikely that those will match.  Your best bet is to have some custom made locally/nearby, if possible, I guess.

What kind of place accepting a custom-made for earpad? :/
