A system for a full-brimmed hat capable of accommodating a headset includes a full-brimmed hat and a headset. The full-brimmed hat allows users to simultaneously wear the headset and obtain full protection from harmful sun rays while also providing shielding from the sunlight. The full-brim is designed with brim joints which are adjusted by fasteners. The brim joints open the holes on the sides of the full-brimmed hat, and the earpieces of the headset are placed in the holes. The frame of the headset rests on top of the full-brimmed hat, which accommodates both a large headset and a small headset.
