Abstract: Audio apparatus comprises a base unit including circuitry for generating electrical signals representing sounds and at least one earphone adapted to receive the electrical signals and to reproduce sounds represented by the signals, in which the apparatus is provided externally with a terminal arranged so that it can be positioned in use in contact with or in close proximity to the surface of the user's body. The circuitry is arranged to supply to the terminal signals which are transmitted through the user's body, the or each earphone is provided with a terminal arranged so that it can be positioned in use in contact with or in close proximity to the surface of the user's body so as to receive signals transmitted from the terminal through the user's body, and the or each earphone includes receiving circuitry arranged to receive the signals. The earphones may be embodied in a pair of spectacles, and may be adjustable between a first position behind the ear and a second position in or more adjacent the ear.
