ABSTRACT:
An earpiece which takes the form of a pouch made of a plastics foil which surrounds a less pliant plastics tube in an airtight manner and is filled with a sluggishly moving jelly-like paste.
A not readily movable compression ring provided with a funnel shaped portion which is clear of the tube ensures that the pouch is filled in such a way that during use the pouch perfectly engages with the inner wall of the auditory canal.
