The material is like a faux suede and is a deep black. I AM FURIOUS! Heres what you want to know. Awwesome productHad to buy one size bigger but working well. It shows the inputs, adjustment levels, and it will display when the stream is Dolby Atmos or DTS:X, but no other format. After wearing these once in awhile for about two weeks I found that they became more comfortable and am very satisfied with my Birkenstocks. Very spacious and sturdy shelves. Soles themselves lok sturdy but it is taking my feet a little while to become accustomed to them. two weeks ago the loop portion that goes over the ear broke where it slides onto the earpiece unit as extra support. Metal frame/legs are lightweight yet sturdy.
