1. A method comprising:
- receiving, in a first earpiece of a headphone, a magnetic field emitted by a magnetic field source associated with a second earpiece of the headphone;
determining an intensity of the magnetic field;
determining whether the intensity of the magnetic field has reached a threshold; and
in response to the intensity of the magnetic field reaching the threshold, performing an operational mode associated with at least one of the headphone or a device in communication with the headphone.

Abstract
An on/off head detection system uses magnetic field intensity to determine a configuration, position and/or orientation of a headphone, including whether a headphone is on or off a wearer'"'"'s head. The system includes a magnetic field sensor configured to detect a magnetic field emitted by a magnetic field source associated with an earpiece of the headphone. A control module determines an intensity of the magnetic field and whether the intensity of the magnetic field has reached a threshold. An operational mode associated with the headphone or an associated device is performed in response to the intensity of the magnetic field reaching the threshold.
