A headset which consists of an ear hook and a holding ring that are interconnected by means of an attachment element formed by a hinge, which is made of a deformable, flexible material that may be an elastomer, such as EPOM, TPE or Santroprene(R)The hinge has a four-sided hole in which one end of the ear hook may be received, said end being formed with a four-sided shape in dimensions corresponding to the hole. Teeth are formed in the hole which are capable of cooperating with depressions formed on the four-sided end. The invention provides an attachment element which may be manipulated several times when adjusting the position of the ear hook relative to the holding ring, without play occurring in the hinge at any time, since there are no mutually movable slide bearing parts, such as shafts that can slide. In other words, a stable attachment is ensured between the ear hook and the holding ring in the positions selected by a user. In addition, it is possible to displace the ear hook in the hinge by mutual displacement of the positions in which the teeth engage the depressions.
