[Elecraft] Sony MDR-7506 replacement pads?

[Frank O'Donnell]

The pads on my nearly ancient MDR-7506's have now officially given up 
the ghost -- both are long-tattered, and one has come off entirely and 
refuses to be reinstalled.

I've read various messages here on pad replacements for these and other 
headphones, comments on various pad types including OEM vs velour, etc.

The one thing I'm stuck on that this point is that, on vendor sites like 
Amazon, I see reviews where it's mentioned that pads can cause a 
significant change in the headphones' sound. I've noticed for various 
pad types.

So a question for MDR-7506 owners who are picky about sound -- can you 
recommend a specific pad that definitely doesn't cause any change in 
that regard?

Thanks and 73,
