Headphone interaction with media playback system

A wearable playback device comprising:

• at least one network interface;
• at least one audio transducer;
• at least one processor;
• at least one wearable housing carrying the at least one network interface, the at least one audio transducer;
• and the at least one processor;
• and
• at least one non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the wearable playback device is configured to:
• establish connection of the wearable playback device to a streamer device via a personal area network;
• detect a particular set of one or more trigger conditions to transition playback of the audio to the wearable playback device;
• in response to detection of the particular set of one or more trigger conditions, cause, via the at least one network interface, the streamer device to send, over the personal area network, at least one audio signal representing the audio in at least one input data stream received via an audio/video input interface of the streamer device;
• receive, via the at least one network interface over the personal area network, the at least one audio signal;
• and
• play back the at least one audio signal via the at least one audio transducer.

At least one non-transitory computer-readable medium comprising program instructions that are executable by at least one processor such that a system is configured to:

• receive, via an audio/video input interface of a first device from a television, at least one input data stream comprising audio;
• establish connection of a second device to the first device via a personal area network;
• detect, via the second device, a particular set of one or more trigger conditions to transition playback of the audio to the second device;
• in response to detection of the particular set of one or more trigger conditions, send, via at least one first network interface over the personal area network, at least one audio signal representing the audio in the at least one input data stream;
• receive, via at least one second network interface over the personal area network, the at least one audio signal;
• and
• play back the at least one audio signal via at least one audio transducer of the second playback device.
