I bought the Brainwavz Round Pads Hybrid. They are much more comfortable than the originals because they are slightly thicker and so my spoons don't touch the headphones.

The ear pads can be removed. To do this, carefully pull the pad aside at any point and you can then see how it is attached. Wash it by hand with a little detergent and let it dry for several hours. For replacement please contact us via our customer portal at http://support.corsair.com/. They are currently not available for direct purchase via our webshop at https://www.corsair.com. A version with imitation leather is not available.
