The original earmuffs my G930, the artificial leather layer dissolves in contact with moist skin or hair, with time. That's why I bought me this fabric, which look smart, are flexible and can absorb moisture and release it again without falling apart. However, the rear support and leatherette, but this is not critical. FYI: If the artificial leather layer of the main bracket begins to crumble, the best please the entire artificial leather layer, teaching them about the trash pull. It is a Biesterei to distribute the Kunstlederbröckchen anywhere in your home! ;)
