Abstract
An ear bud or cone having multiple protruding, convex and soft elements which are configured to be deformed during insertion, extraction and operation in the ear canal of a person. The soft elements are cushion shaped and thus able to adapt to any shape of the ear canal without exerting excessive force to portions of the ear canal.
