A hearing device, in particular a hearing system, is designed more acoustically stable with regard to feedback as well as more mechanically stable with regard to external influences by a sound emission tube for direct connection to an output nozzle of an earpiece of a hearing device. The sound emission tube has an outer sheath made from a first plastic and an inner wall made from a second plastic that is more elastic than the first plastic. The outer sheath and the inner wall are produced by 2-component injection molding. The inner wall damps vibrations from the earpiece outward or shocks from the outside to the earpiece. Conversely, the outer sheath provides for the mechanical stability and the sufficiently rigid mounting of the earpiece.
