Abstract: Head wearable devices and methods are disclosed where a head wearable device includes a headpiece including a headband and an occipital basket attached to the headband, and a first housing attached to the headband. A depth adjuster is attached to the first housing and configured to change, by controlling a distance between the occipital basket and the first housing, a depth of the headpiece. A second housing is attached to the occipital basket, and a headband adjuster is attached to the occipital basket to change a circumference of the headpiece by controlling a distance between respective opposing ends of the headband and the second housing.
