  • Example techniques described herein relate to transitioning a playback session between wearable playback devices, such as “smart” headphones and earbuds, and playback devices of a zone-based media playback system. Further example techniques relate to transitioning a playback session between portable (e.g., battery-operated, carryable) playback devices and playback devices of a zone-based media playback system. Such transitions are referred to herein as “swaps” or “playback session swaps.” Such exemplary swap techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud). Further, some exemplary techniques may reduce the extent of user input (or other user involvement) involved with transitioning playback as compared with some other techniques.

  • wearable playback devices are designed for relatively private listening compared with the portable playback device 710 c and the playback device(s) 110 , the user is less likely to desire to group the headphones for synchronous playback with these types of devices.
  • Other example implementations may vary this control scheme.
  • the initiating playback device has the potential to identify a different playback device as the source or target than the user intended, perhaps due to unique acoustic characteristics of the environment causing an audio chirp emitted from a further away playback device to appear to be nearest.
  • a grouping between the sources and targets of the potential swap occurs, causing synchronous out-loud playback on the sources and targets of the potential swap.
  • a push-group is performed, which causes the initiating playback device and the nearby playback devices to play back the on-going playback session in synchrony.
  • the soundbar-type playback device 110 h forms a bonded zone that includes the soundbar-type playback device 110 h and the headphones 710 a . This may be considered to be the same bonded zone as the Den 101 d or a new bonded zone.
  • the headphones 710 a send a message to the soundbar-type playback device 110 h to start streaming the HT audio stream.
  • Parking the satellites on the second LAN allows the satellites to remain contactable (e.g., to eventually re-form the bonded zone when transitioning back to the home theater mode) and to receive updates on the state of the media playback system 100 (e.g., state variable events).

  • detecting proximity between the source playback device and the target playback device triggers a swap. For instance, detecting that a source playback device and a target playback device of a pre-defined swap pair are in proximity may initiate a swap of a playback session between the source playback device and the target playback device.
  • the source and target playback devices of a swap are defined by proximity of the source playback device to the target playback device.
  • Example proximity detection may be implemented at one or more ranges, such as proximity to the media playback system 100 (i.e., the home or some other known location), proximity to a zone, or proximity to a playback device.
  • the paired control device 130 a may compare current signals and/or sensor data to the stored profile(s) corresponding to the zones. For instance, the paired control device 130 a may determine the closest match to the current signals and/or sensor data by comparing how many markers in each profile are present in the current signals and/or sensor data. The paired control device 130 a may also threshold the markers by determining proximity to a particular zone when a pre-determined number (or percentage) of markers in the stored profile of the particular zone are also present in the current signals and/or sensor data. While these operations are described by example as being performed by the paired control device 130 a , other devices such as the portable playback device 710 and/or the bridge device 860 may also determine the profile and/or detect proximity using the stored profiles.
