Abstract
A wireless headset includes a microcontroller and a first earpiece and a second earpiece to provide audio output to a user. The wireless headset includes a flexible headband coupled to the first earpiece and second earpiece and a headband profile state sensor. The headband profile state sensor detects when the headset is in a headset un-worn headband gesture state and a worn headband gesture state by detecting a change in resistance value at a headband profile state sensor when a distance between the earpieces is increased and decreased thereby flexing the headband. A headband state circuit includes a comparator to detect a change in the resistance at the headband profile state sensor. The headband state circuit may be dynamically adjusted via bias gain used to ensure the headband state circuit is able to detect transitions between the headset un-worn headband gesture state and the headset worn headband gesture state.
