Abstract
Abstract An adjustable headset includes a headband and a pair of earpieces attached to the ends of the headband. A number of recesses are formed in a housing. The earpieces are attached to one end of the housing. A retaining device is coupled to the headband. A pair of pawls are formed on the retaining device and are engageable with either recess of the housing when the retaining device and the headband are inserted into the housing. The headband is adjustable relative to the earpieces by an engagement between the pawls and the recesses.
