The present disclosure relates to an earpiece (32) for an ear (10). The ear (10) comprises a concha cavity (22) at least partially delimited by a concha floor (26), a concha side wall (28) and a concha ceiling (30). The concha side wall (28) connects the concha floor (26) to the concha ceiling (30), wherein the surface of the concha ceiling (30) has a normal at least a component of which being directed towards the concha floor (26). The earpiece (32) comprises a
peripheral skirt (34) comprising a positioning skirt portion (36) which in turn comprises an outer skirt surface (38) and an inner skirt surface (68), wherein a transition from the outer skirt surface (38) to the inner skirt surface (68) occurs at a skirt edge (40). The skirt edge (40) extends at least partially circumferentially around a central axis (CA) of the earpiece (32), wherein the earpiece (32) is adapted to be moved to a use position, at least partially within the concha cavity (22), in a direction parallel to the central axis (CA), during
insertion of the earpiece (32) into the ear (10). When the
peripheral skirt (34) is in a non-influenced condition, at least a portion of the inner skirt surface (68) faces the central axis (CA). The earpiece (32) is such that the positioning skirt portion (36) is adapted to assume the use position at least partially within the concha cavity (22) whereby: - at least a portion of the outer skirt surface (38) abuts at least a portion of the concha ceiling (30), - the skirt edge (40) is located closer to the concha floor (26) than the outer skirt surface (38), and - the skirt edge (40) is spaced from the concha floor (26).
