Abstract
A cushion configured to be secured to an ear cup of a headset and/or hearing protection device. The cushion defines an inner opening and includes a contact surface along a periphery proximal part of the cushion. The contact surface is configured to abut against and contact a user's head around an ear of the user when the headset and/or hearing protection device is worn by the user. The contact surface of the cushion has a predetermined height profile where respective height values of the predetermined height profile at multiple locations of the contact surface vary about a center or center point of the cushion. The locations are located nearest or towards the inner opening, and a first height of the predetermined height profile is a globally largest height. The first height is located in an upper front-facing part of the cushion.
