The invention relates to an alarm device (1) for a pilot's headset (3), and to a pilot's headset with such an alarm device. The alarm device comprises: a position sensor (11), which detects its own tilt relative to an initial position or to horizontal; and a measuring device (12) for determining how long the tilt detected by the position sensor has exceeded a given tilt tolerance limit. In addition, the alarm device has a means (13) of setting off an alarm signal when the detected duration of being over the tilt tolerance limit is greater than a pre-set maximum duration.
