Need Replacement Ear Pads for James Donkey 712 Headphones, Unable to Find Online

I’ve been using the James Donkey 712 headphones for a long time and have been really happy with them. However, over time, the ear pads have worn out and deteriorated. I’ve searched online but haven’t been able to find replacement ear pads anywhere. Since I’m satisfied with the headphones and don’t want to replace them, I would appreciate it if someone could assist me in finding replacement ear pads. I’m hoping for a solution that allows me to keep using the headphones I enjoy without having to buy an entirely new pair. Thank you for any help you can provide!
