charging case is less than 1%. The headset cannot be charged with the charging case in this case.

Hint

The remaining battery charge of the headset may be different on the left and right sides depending on how you use them.
When checking the remaining battery charge on an iPhone/iPod touch or Android smartphone while using both headset units, the
remaining battery charge of the headset unit with less remaining battery charge between the left and right headset units is
displayed. When using only one headset unit, the remaining battery charge of the headset unit you are using is displayed.

You can also check the remaining battery charge of the headset unit and the charging case with the “Sony | Headphones
Connect” app. Android smartphones and iPhone/iPod touch both support this app.

Note

If the headset and smartphone are not connected with HFP, the remaining battery charge will not be correctly displayed.

If you connect the headset to an iPhone/iPod touch or Android smartphone with “Media audio” (A2DP) only in a multipoint
connection, the remaining battery charge will not be displayed correctly.

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.
