Abstract
Various implementations include wearable audio devices and related methods for controlling such devices. Some approaches include: detecting a change from an on-head state to an off-head state with a first sensor system; calibrating a second, distinct sensor system after detecting the change from the on-head state to the off-head state; detecting a change from the off-head state to the on-head state using the calibrated second sensor system; and adjusting an operating state of at least one function of the wearable audio device in response to detecting the change from the on-head state to the off-head state or detecting the change from the off-head state to the on-head state.
