Abstract
The inventive microphone cover for hearing devices for at least partially covering openings (6) arranged at the outside of the hearing device comprises a ring (2) with racks (4) overdrawing the opening of the ring (2). The outer diameter of the ring (2) thereby is equivalent with the inner diameter of the corresponding opening (6) of the hearing device such as the ring (2) is at least partly insertable within the opening (6). A stop (11) is provided advantageously within the opening (6) at a desired depth (t) to define the exact insertion position of the microphone cover (1).
