Replacement pads for ATH-AD500X

When I recently had my 500X’s apart for a proper cleaning (they are my most used cans), I noticed the left pad showing some signs of age.

I would like to keep velour pads on these as I found pleather to turn “ugh” to quickly.
So far, I found three options that may work.

ATPT-AD900XPAD 30€ Keeps it stock
Shure HPAEC 940 25€
Shure HPAEC 1840 22€
beyerdynamic DT-770 28€

Are the 500X's an odd shape that nothing fits? Is there anything I am overlooking?

So far I found one thread elsewhere that kind of goes in the direction.
