A hearing device comprises an ear-piece which is designed to be worn at least partially in an ear canal of a user of the hearing device. The ear-piece comprises a vent passage connecting the ear canal with the atmosphere. The vent passage has an inner opening towards the ear-canal and an outer opening towards the atmosphere. The ear-piece further comprises a vent extension. The vent extension is a protrusion extending the vent passage beyond the body of the ear-piece. The vent extension is adapted for abutting on a surface of the body of the user and is thereby inconspicuous and/or contributes thereby to retention. A method for manufacturing such a hearing device is also disclosed.
