Description

Object description

One part of the headset is formed of metal ear phones. These ear phones are formed of 2 metal pieces that are attached to the ear pieces which are oval shaped metal plates with circular metal pieces attached to one side and white padded cotton coils that fit over the ears. Attached to the underside of these ear pieces are two army green (with yellow and red dotted lines running diagonally around the wire) textile wires. This wire spits and at one end has a plastic bell shaped handle that has a large metal rod attached to the centre of it which would plug into another piece of equipment. The other end of the wire is connected to a cylindrical metal tube that is mostly hollow. The inside of the tube has a circular gold coloured disk with holes in it and at the end of the tube there is a rubber piece where the mouth would fit into.
