C-Pads have an undergone an upgrade evolution over time, approx the 10th variation since I came up with them years ago.
They are basically circumaural (the C) Beyer velour pads on adapters for adding comfort, soundstage, etc to fit onto Grado headphones. They are fronted with black sound acoustic foam, for further wild hair protection against "grattle" and soaking up reverberation from the closed pads and soundboard. Past V1-V8 models had cloth.
New V10 I've created another new version of C-Pads. The ports are still shaped like little ears to catch and extract bouncing sound waves. The added foam helps in that respect too. No more plastic frame, all wood now.
Silver pads are default and black pads are $10 more. You will get silver if black is not paid for at the time of order. Eventually if the pads themselves need changing, that has been planned for and you can buy some from Beyer direct and put them on yourself (can be tricky the first time, heat inside flange with blow dryer).
