Abstract
A wireless audio device includes one or more electroacoustic transducers and a first wireless transceiver. The device also includes a processor configured to (a) process audio signals received by the transceiver in a first received signal and communicate the processed audio signals to the transducer(s) to cause the transducer(s) to output sound pressure waves, (b) determine that a characteristic of a second received signal independent of the first received signal surpassed at least one threshold, and (c) change a state of the audio device based on the determining.
