You need the urethane that goes around the driver, the urethane that goes between the wooden housing and the frame, and a new set of ear pads. Part #'s are below.

2-116-074-01 - small urethane

2-116-075-01 - large urethane

2-116-077-01 - left ear pad

2-116-078-01 - right ear pad

I have replacement ear pads already. Damn, I should've ordered a bunch of those Urethane rings. It's probably a common type of foam. Wish there was a place that still had some in stock.

But fortunately urethane foam is quite common and cheap. We just need to find out the density of the foam used in the R10's and buy a bunch at the correct thickness. Cutting out little doughnut shapes would be very simple.

Let me know how that goes )
