Sheepskin Leather (1 Pair Left & Right) We created this model due to the limited availability of quality pads to maintain the incredible experience these headphones already give. When you take soft, supple sheepskin and wrap it in dense, slow rebounding memory foam, you increase isolation, comfort and sound stage. The sheepskin and foam wrap create a tight but comfortable seal on your head, even if you wear glasses, to ensure that our discerning listeners have a great headphone experience.
