Does anyone know a place to source some coarse open cell foam in 1/16" thick sheets/rolls (similar to the stuff in Stax or Sennheiser headphones)?

I want to make some acoustically transparent pads to go inside headphones that put your ear against bare plastic, for some extra comfort. I have some speaker grille cloth I'm going to try using too, but I'd like to figure out where I can get several square feet of the foam. So far I've only been able to find open cell as thin as 1/8", with any of the 1/16" ones having a skin on them or being closed cell.

Thanks in advance for any help.

Hmm...check 3M.

Where'd you find 1/8th? I'm sorta looking at refoaming my QP85.

I think McMaster-Carr had 1/8" open cell, I'm not really sure since it was a few weeks ago that I last tried to find some.

I think I'm gonna order some 1/4" coarse open cell foam and see if it's properties are close enough to what I want, and just slice it thinner myself. The foam rings inside many AKG headphones are 1/4" thick too, so I may be able to use it to create my own replacements. I still would like to find some kind of source for it in 1/16" sheets, even if it means having to go to a more fine celled structure...
