I bought a pair of Cleer NCs from here about a year ago, I love them and use them basically every day. Over the year of use, however, the earcups have started to wear down and tear in places. It doesn't change the performance of the headphones that much, but for the sake of appearance I would like to replace them with new ones. The problem is that Cleer seems to have stopped making the headphones since I bought them. Are there any third party earcups I can put these headphones?
