Checking the remaining battery charge

You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case by the following operations.

Checking the remaining battery charge of the headset

  • If the indicator (orange) on the charging case lights up when the headset units are set in the charging case or when the charging case lid is opened or closed while both headset units are set in the charging case, the remaining battery charge of the headset units is between 94% and 1%.
  • If the indicator on the charging case does not light up when the headset units are set in the charging case or when the charging case lid is opened or closed while both headset units are set in the charging case, the remaining battery charge of the headset units is at less than 1%.

When the remaining battery charge of the headset units drops to 20% or less while the headset units are in use, or when the remaining battery charge of the headset units is at 20% or less when the headset is turned on

If you hear a notification sound and the voice guidance say, “Low battery”, charge the headset as soon as possible.

When the battery becomes completely empty, you will hear a notification sound and the voice guidance say, “Battery is empty”. Then, the headset automatically turns off.

When using the headset by connecting to a computer

When the headset is connected to a computer, the icon indicating the remaining battery charge is displayed on the “INZONE Hub” screen in 4 levels: “100%”, “70%”, “50%”, and “20%”.

The remaining battery charge is also displayed over 100 levels in [Device Information] on “INZONE Hub”.


Checking the remaining battery charge of the charging case

  • If the indicator (orange) on the charging case lights up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is between 30% and 1%. The charging case cannot sufficiently charge the headset with this remaining level of battery charge.
  • If the indicator on the charging case does not light up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is at less than 1%. The headset cannot be charged with the charging case in this case.

Hint

  • You can also check the remaining battery charge of the headset unit and the charging case with the “Sony | Headphones Connect” app.

Note

  • The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining battery charge.
