Abstract
To secure earphones in the auditory canal of a user, ear tips are used. In an improved earphone, which reduces or avoids pressure sores occurring in the ear of the user, a hard stub of the housing no longer protrudes as hitherto into the ear tip, and instead a soft receiving tube of the ear tip is secured in the housing. By means of this inverse receiving principle, the ear tip can better conform to the auditory canal and thus enhances the wearing comfort. For assembly, the tube is plugged into an opening in the housing so that a projection of the tube engages in a depression or inner shoulder behind the opening and thus secures the ear cushion on the housing.
