The composite cover wraps around the annular cushion and defines an inner-side portion, an outer-side portion and an ear-abutting portion. The ventilative and air-tight layers are respectively formed by the outer-side portion and a composite of the inner-side and ear-abutting portions or by a composite of the outer-side and ear-abutting portions and the inner-side portion. Therefore, the ventilative layer and the annular cushion form a good heat dissipation path to have excellent air-permeable property, and air-tight layer provides an improved acoustic field effect. ## Claims ### Claim 1 A headphone ear cup, comprising: an annular cushion provided at a center thereof with a sound hole; and a composite cover having a ventilative layer and an air-tight layer, and wrapping around the annular cushion to define an inner-side portion surrounding the sound hole, an outer-side portion opposite to the inner-side portion spacedly and remote from the sound hole, and an ear-abutting portion connected between the outer-side portion and the inner-side portion; wherein the ventilative layer has an air permeability higher than that of the air-tight layer, the ventilative layer is formed by the outer-side portion and the ear-abutting portion, and the air-tight layer is formed by the inner-side portion; wherein the ventilative layer and the air-tight layer are made from different material. ### Claim 2 (depends on 1) The headphone ear cup as defined in claim 1, wherein the outer-side portion and the ear-abutting portion are made of a same material. ### Claim 3 (depends on 1) The headphone ear cup as defined in claim 1, wherein the annular cushion has an annular body and at least one air-permeable portion arranged at an outer periphery of the annular body; two sides of the at least one air-permeable portion are connected to the ear-abutting portion and the outer-side portion, respectively; the at least one air-permeable portion is made of a porous material having a density lower than that of the annular body. ### Claim 4 (depends on 3) The headphone ear cup as defined in claim 3, wherein the annular body of the annular cushion is abutted with the inner-side portion. ### Claim 5 (depends on 3) The headphone ear cup as defined in claim 3, wherein the air-permeable portion of the annular cushion has an annular shape and surrounds around the sound hole. ### Claim 6 (depends on 5) The headphone ear cup as defined in claim 5, wherein the air-permeable portion of the annular cushion is abutted with the annular body. ### Claim 7 A headphone ear cup for disposing on a headphone, the headphone ear cup comprising: an annular cushion provided at a center thereof with a sound hole;
