I don't know what type of material they use around headphones, their intention seem to appear it like a shiny leather but they peel off and piss me off.
I have this Philips, it's I think 2004 model which is kind of acceptable to peel off today but for years it's the same. Today I brushed it and cleared from all that material.
This is a demo headphone in the store, 2016 model Marshall and it's peeling too.
These are the high end brands' top models, is it that difficult to use a quality material ?
