Abstract
Headset for connection to a telephone apparatus, said headset comprising a capsule with a built-in receiver, and on which there is mounted a boom with a microphone. The headset is connected to a telephone apparatus by means of a wire with associated jack connection, and the headset has associated amplification and adjustment circuits for both the microphone and receiver, manual operating elements for the setting of said amplification and adjustment circuits, and switch elements for changeover depending partly on the type of microphone in the telephone apparatus and partly on the polarity of the telephone apparatus' microphone and receiver wires. The amplification and adjustment circuits are built into the headset capsule, so that the use of a separate connection box is avoided, and the manual operation elements are placed on the capsule. The switching elements consist of a multi-position switch, which is placed in the capsule in such a manner that it is accessible for operation.
