A headset (1, 10, 30) e.g. for use in connection with wireless communication by means of Bluetooth technology in connection with mobile telephones, PSTN telephones and the like, which comprises a housing (2, 3, 11, 28) with a transducer (5, 12, 27) in the form of a speaker, as well as a microphone (4, 14, 29) and an ear hook (6, 23, 28). In a first embodiment, the housing may be constructed as two shells (2, 3) which may be opened and closed so that all mechanical parts may be concealed on the housing when the headset (1, 10, 30) is not in use, thereby ensuring that the various parts are not damaged when the headset is stored in a pocket. The shells (2, 3) may be interconnected by means of a hinge (7, 8) which has an axis disposed in the same plane as the surface of the shells. Alternatively, the shells may be arranged such that the axis is disposed in a perpendicular plane relative to the surface of the shells. In a second embodiment, the housing (11, 28) is formed by a closed housing from which the ear hook (23, 31) and/or the microphone 13, 26) may be moved in or out. The invention provides a headset (1, 10, 30) which is extremely easy to use, and where all mechanical and electrical parts are well protected when the headset is not used. Furthermore, all embodiments may be provided with a lock which may be mechanical and/or electrical, which ensures that only the right user can use the headset.
