Abstract

Headset apparatus, particularly applicable for use with a mobile phone (1), or similar equipment, is connected via signal converter (5) which converts electrical signals received via the phone (1) to an acoustic signal for transmission via sound pipe (7) to an earpiece (11) of a headset (10). The headset (10) comprises an optical microphone (12) which modulates a light signal received on optical fibre (8) from a light source (14). The modulated light signal is returned to opto-electronic converter (17) which converter (17) generates an electrical signal conveying any acoustic signal received by the microphone (12) to mobile radio (1). The invention avoids the requirement for any electrical connection between the mobile radio and a headset (10), and thus avoids any radiation hazard which could otherwise due to radiation from the antenna of a mobile phone being conducted through the electrical conductors of a conventional headset.
