Abstract: Aspects of the subject technology provide improved techniques for determining a state of an audio device, including reduced power techniques for determining if an earbud is currently being worn in a user's ear or not. In aspects, a potential state change in an audio device may be detected, and in response measurement of the state of the device may be initiated, such as by emitting an audio signal and then determining the state of the audio device based on a sensed version of the emitted audio signal.

Abstract: Aspects of the subject technology provide for calibration of audio devices in a case. In some implementations, the calibration techniques may include detecting that an audio device is docked in a case and a lid of the case is in a closed position, where the audio device is positioned in a cavity of the case. In addition, the calibration techniques may include emitting a test audio signal from a speaker of the audio device into the case. The device may include receiving, in response to the test audio signal, a received signal at a sensor inside the case. Moreover, the device may include obtaining a correction for the audio device based on the received signal.
