摘要

First (1) and second (2) independent earpieces have an outer covering, an ear hoop (12), a source of audio signals, a frame, an electro-acoustic converter and an inner covering. The words 'outer' and 'inner' here relate to the position of the user's ear during use. The outer cover and the frame are interlinked and include the source of audio signals between them.
