An energy saving headset is provided. The headset includes a power management unit 150 operable to reduce power consumption of the headset when no user is present. The power management unit 150 detects the presence of the user using capacitance type detection. Capacitive detection is advantageous because it provides a flexible and reliable sensor and can accurately detect whether a user is present by detecting either the user's approach or contact. Further, in various embodiments, the sensitivity of the capacitive sensor is adjusted to account for changes in environmental conditions such as user movement and, for example, the presence of water or sweat on the headset, Furthermore, the reliability of detection can be improved. Furthermore, the present invention relates to a headset that controls other functions or controls external devices using a user presence signal based on capacitance type detection.
