Abstract: Various implementations include wearable audio devices and related methods for controlling such devices. Some approaches include controlling a wearable audio device by: determining a magnitude of an acoustic transfer function based on an electrical signal from an internal microphone and an audio signal from an acoustic transducer at one or more predetermined frequencies; calibrating a proximity sensor; detecting a change in the state of the wearable audio device from one of: off-head to on-head, or on-head to off-head using both the calibrated proximity sensor and the magnitude of the acoustic transfer function; and adjusting at least one function of the wearable audio device in response to detecting the change from the on-head state to the off-head state or detecting the change from the off-head state to the on-head state.

Abstract: This document describes a method that includes receiving an input signal representing audio captured by a sensor disposed in an active noise reduction (ANR) device, determining, by one or more processing devices, that the ANR device is operating in a first operational mode, and in response, applying a first gain to the input signal to generate a first amplified input signal. The method also includes determining, by the one or more processing devices, that the ANR device is operating in a second operational mode different from the first operational mode, and in response, applying a second gain to the input signal to generate a second amplified input signal, wherein the second gain is different from the first gain. The method further includes processing the first or second amplified input signal to generate an output signal, and generating, by an acoustic transducer, an audio output based on the output signal.

Abstract: A method of transferring audio signals from an analog audio source to an audio sink, where the audio sink has a multiple-pin connector. A cable is coupled to the audio source and to the multiple-pin connector of the audio sink, where the cable is constructed and arranged to carry audio signals. The audio sink detects a return signal provided to the audio sink over the cable, where the audio sink is configured to interpret the receipt of a return signal as indicating that an audio source is operably connected to the audio sink by the cable. Responsive to this detecting, the audio sink receives audio signals from the audio source over the cable.
