Like all RHA headphones, these are beautifully designed. These inear headphones are made using Ceramic Transducers. Designed to be used with an external amp these reference quality headphones come with removable cords, balance and unbalanced cables, a quarter inch adapter, storage case and a large assortment of gels so you can get a proper fit. There is also a stainless rack to hold the extra gels. RHA did not shrink wrap this model headphone, but they were opened and checked out so we are listing them as open box.
