Beschreibung
Zusammenfassung:	This invention relates to an ear muff having composite soft pad, comprising a composite soft pad and a wrapping cover covering the surface of the composite soft pad, wherein the composite soft pad has an annular main body and a ventilation part disposed to the outer peripheral surface of the annular main body; and the ventilation part is made of a porous material with density lower than that of the annular main body. Accordingly, the annular main body made of material with higher density can maintain the sound output performance of the headphone while the ventilation part made of material with lower density can provide good heat dissipation effect, enabling the ear muff to have both effects of cool feeling and good sound field creation.
