PROBLEM TO BE SOLVED: To provide an earmuff in which sound insulation is maintained well even when a wired earphone having a cable is attached to an auricle. An earmuff (51) has an annular pad portion (3) having a main body portion (1) and a contact surface (32) attached to the main body portion (1) and brought into contact with a head (H) during use. ) And. Further, in the pad portion (3), the inner peripheral surface (36) and the outer peripheral surface (37) are connected and opened to the contact surface (32) so that the position shifts in the circumferential direction toward the main body portion (1). It has a notch (31) formed in.
