Ear pads

I recently bought a pair of Logitech G930s and They're pretty nice all around the only minor issues I have are the ear pads since they are made out of some kind of fake leather and can get a bit uncomfortable after a while.  

So I was wondering if anyone knew where I could get better replacement ear pads
