A hearing protection device has a base () configured for connecting to a lateral portion of a protective helmet (), an ear cup () configured for covering an ear of a user, and a support () connecting the ear cup () to the base (). The support () has a first arm () and a second arm () each having an upper part connected to the base () by at least one connection member () and a lower part connected to the ear cup (). The at least one connection member () is elastically deformable to allow relative movement of the upper part of the first arm () relative to the upper part of the second arm (). The hearing protection device is movable between an active position, in which the ear cup () is configured to cover the ear of the user, and an inactive position, in which the ear cup () is configured to be spaced apart from the ear of the user.
