Oppo PM3 replacement earpads

Less than 4 years of owning these cans and i had to change the OEM earpads twice since oppodigital used a very cheap pleather. Since they have officially shut down and although they are selling the OEM earpads directly throu customer support, i want to find another option that can keep as much of the original sound as possible.
I tried many pads and so far the M50x pads are the better choice, but they make the mids go way back and sound kind of boxy with the thick foam they use at the hole. I want to try the dekoni’s since they have less foam but they are expensive and want to do my research before investing.

Have you got the right earpads?
