I don't believe you will find genuine leather earpads that are an exact match, but if you are in the US, this is their contact page... http://en-us.sennheiser.com/service-support/contact-center/how-to-reach-us
Looking to buy a cheap custom built pc. I want a dedicated computer for a headphone listening station. Doesn't have to be top of the line, just want it to be upgradable and able to add extra HDDs and such. Send me pm of your offer with specs, price, pics.
I ordered both and sent the M-100s back. I think everything about the momentums is better...details, bass, soundstage, comfort, and even looks. It was a closer match then I make it sound, I still may pick up the m-100 again. But yah, I think you made the right decision.
