Abstract
A method and apparatus are provided for allowing a user to change the stiffness of their headband, thus changing the clamping force of the headset. The section properties of the headband equivalent spring, which is a cantilevered beam, are changed by engaging a secondary spring, which is also a shorter cantilevered beam. The change is achieved by manipulating the effective length of the secondary spring, which can be accomplished with a set of clamps. Thus, the stiffness of the headband can be modified to the desire of the user.
