An earmuff includes: a casing; a baffle board; and an ear pad including an engagement member, the engagement member being an outwardly extended part of a skin member of the ear pad. The ear pad is fixed at a front of the baffle board with the engagement member constrained to an outer surface of either of the baffle board and the casing or both by a ring-shaped elastic member, and the ear pad fixed and the baffle board define a front air chamber.
