The ear cushion is configured to abut the head of the user along an annular contact surface of the ear cushion and to abut or face a housing of the earphone along an annular attachment surface of the ear cushion when the user is wearing the earphone in its intended position, thereby reducing the level of sound entering the ear canal of the user from the environment. The ear cushion further comprising an annular exterior surface and an annular interior surface each extending from the contact surface to the attachment surface and facing respectively the environment and the ear canal of the user when the user is wearing the earphone in its intended position. The ear cushion further comprising a foam core () having a first acoustic impedance, and a cover having a first portion extending across the exterior surface and a second portion extending across the contact surface. The first portion of the cover has a second acoustic impedance that is greater than the first acoustic impedance, wherein that at least one first subportion of the second portion of the cover has a third acoustic impedance that is smaller than the second acoustic impedance.
