From the looks of things, the mod consists of:
- Dynamat Extreme all over the back of the headphone while leaving the "holes" open.
- Some amount of tissue paper/toilet paper behind the oval white fabric screen. I'm guessing this is the same size as the screen?
- A 1cm thick paper ring ontop of the oval white fabric screen.
- Some shelf liner and mesh, presumably to hold down the front/provide some protection/for comfort.
Would this be correct?
