A headset comprising: an element (13, 15, 17, 19, 21) to be held to the head of a wearer, a headband coupled to the element and configured for engaging the head of the wearer to hold the element thereon, the headband including at least two headband sections (12, 14, 12a, 13a, 14a) coupled to pivot with respect to each other, a torsion spring positioned between the sections, portions of the torsion spring coupled to the sections for acting on the sections with a torsion force, and an adjustment member having one end configured for engaging one of the headband sections and another end that is coupled with the torsion spring, the adjustment member being operable for rotating and adjusting the torsion force of the torsion spring to adjust the torsion force on the sections, characterized in that: the adjustment member includes a bolt having a shaped first end configured, in a locked position, to seat inside a shaped opening of said one headband section to prevent rotation and having a second end configured to be coupled with the torsion spring, the bolt being movable to an unlocked position, for selectively disengaging the shaped first end from the shaped opening of the said one headband section so the shaped first end of the bolt is individually rotated to wind the second end and the torsion spring and adjust the torsion force acting on the headband sections. an element (13, 15, 17, 19, 21) to be held to the head of a wearer, a headband coupled to the element and configured for engaging the head of the wearer to hold the element thereon, the headband including at least two headband sections (12, 14, 12a, 13a, 14a) coupled to pivot with respect to each other, a torsion spring positioned between the sections, portions of the torsion spring coupled to the sections for acting on the sections with a torsion force, and an adjustment member having one end configured for engaging one of the headband sections and another end that is coupled with the torsion spring, the adjustment member being operable for rotating and adjusting the torsion force of the torsion spring to adjust the torsion force on the sections, characterized in that: the adjustment member includes a bolt having a shaped first end configured, in a locked position, to seat inside a shaped opening of said one headband section to prevent rotation and having a second end configured to be coupled with the torsion spring, the bolt being movable to an unlocked position, for selectively disengaging the shaped first end from the shaped opening of the said one headband section so the shaped first end of the bolt is individually rotated to wind the second end and the torsion spring and adjust the torsion force acting on the headband sections. the adjustment member includes a bolt having a shaped first end configured, in a locked position, to seat inside a shaped opening of said one headband section to prevent rotation and having a second end configured to be coupled with the torsion spring, the bolt being movable to an unlocked position, for selectively disengaging the shaped first end from the shaped opening of the said one headband section so the shaped first end of the bolt is individually rotated to wind the second end and the torsion spring and adjust the torsion force acting on the headband sections.
