The headset is turned off automatically.

  • If the IR sensor of the headset cannot detect that the headset is being worn because the headset is not worn properly, the earbud tips are not attached properly to the headset, or the IR sensor is dirty, the automatic power off function may activate and automatically turn off the headset. Adjust the fit of the headset to your ears, and if the IR sensor is dirty, clean it with a soft dry cloth.
  • When the automatic power off function is set to [Do not turn off] on the [System] tab of the “Sony | Headphones Connect” app, wearing detection will continue to work and the symptom may be improved.
  • Make sure the battery is fully charged.
