4. The earpiece according to claim 1 , wherein the outer surface extends along a longitudinal axis of the earpiece.

5. The earpiece according to claim 1 , wherein the earpiece housing has a circular cross section, and/or an ovaloid cross section, and/or a rectangular cross section perpendicular to a longitudinal axis of the earpiece.

6. The earpiece according to claim 1 , wherein the receiver housing is off-centered with respect to a longitudinal axis of the earpiece.

7. The earpiece according to claim 1 , wherein the receiver housing has an outer surface in contact with an inner surface of the earpiece housing.

8. The earpiece according to claim 1 , wherein a first distance and/or first area between a first side wall of the receiver housing and a first side wall of the earpiece housing, is larger than a second distance and/or second area between a second side wall of the receiver housing and a second side wall of the earpiece housing, wherein the second side wall of the receiver housing is opposite the first side wall of the receiver housing, and wherein the second side wall of the earpiece housing is opposite the first side wall of the earpiece housing.

9. The earpiece according to claim 1 , wherein the receiver housing is closer to a first side wall of the receiver housing than to a second side wall of the receiver housing, the second side wall being opposite from the first side wall.

10. The earpiece according to claim 1 , wherein the receiver housing is centered with respect to a longitudinal axis of the earpiece.

11. The earpiece according to claim 1 , wherein the vent path is at least partly in the earpiece housing.

12. The earpiece according to claim 1 , wherein at least a part of the vent path is defined by a surface of the receiver housing.

13. The earpiece according to claim 12 , wherein the at least a part of the vent path extends longitudinally along a longitudinal surface of the receiver housing.

14. The earpiece according to claim 1 ,

wherein the first aperture is on the outer surface of the earpiece housing proximal to the vent mechanism and distal to the receiver.

15. The earpiece according to claim 14 , further comprising a second aperture distal to the vent mechanism, the second aperture associated with the vent path.

16. The earpiece according to claim 1 , further comprising a microphone, wherein the microphone is distal to the vent mechanism.

17. The earpiece according to claim 1 , further comprising one or more additional apertures associated with the vent path, the one or more additional apertures and the aperture located closer to the proximal end of the earpiece housing than to the distal end of the earpiece housing.

18. The earpiece according to claim 1 , further comprising a plurality of apertures that are closer to the distal end of the earpiece housing than to the proximal end of the earpiece housing.

19. The earpiece according to claim 1 , wherein the first aperture is at the proximal end of the earpiece housing.

20. The earpiece according to claim 1 , wherein the vent path allows venting outside multiple sides of the receiver housing.

21. An earpiece of a hearing device, the earpiece configured for insertion into an ear canal of a user, the earpiece comprising:

an earpiece housing having a distal end, a proximal end, and an outer surface extending between the distal end and the proximal end;

a receiver comprising a receiver housing, the receiver located within the earpiece housing; and

a vent mechanism in the earpiece housing, wherein the vent mechanism is distal to the receiver;

wherein the vent mechanism is configured to open and close a vent path that is at least partly in the earpiece housing; and

wherein the earpiece has a first aperture on the outer surface of the earpiece housing proximal to the vent mechanism and distal to the receiver;

wherein the earpiece further comprises a first dome located proximal to the first aperture, wherein the first dome has an inner surface extending circumferentially along the outer surface of the earpiece housing; and

wherein the first dome has a vent aperture for provision of fluid communication between a proximal side and a distal side of the first dome.

22. The earpiece according to claim 21 , further comprising a second dome located distal to the first dome, wherein the second dome has an inner surface extending circumferentially along the outer surface of the earpiece housing.

23. The earpiece according to claim 22 , wherein the second dome is configured to prevent fluid communication between a proximal side and a distal side of the second dome.

24. The earpiece according to claim 22 , further comprising second aperture, wherein the second dome is at a longitudinal position that is between a first longitudinal position of the first aperture and a second longitudinal position of the second aperture.
