Instructions are very good, would recommend them for first-time replacement. I’ve done a replacement before, so was able to just do the job. Cups are a little stiff now, but I remember the last set I did were initially a little stiff then softened up. They come with replacement fabric + 3M adhesive for the back side of the cans. Replacing these makes headphones feel pretty new again. Fit is very good, same as original quality in my opinion. ..More
