About charging while using the headset

You can use the headset while charging.

When using the headset while it is charging, charging will stop at approximately 80% (if the battery level is more than 80%, charging will not start). The value is a rough estimate. The value may vary depending on the ambient environment.

Depending on the charging environment (such as the power source or type of USB AC adaptor used), you may hear electrical noise from the headset when it is charging.
Headset functions and operations may not work correctly.


Charging when there is liquid such as water, sweat or foreign matter such as dust on the USB Type-C cable or USB Type-C port can cause accidents such as burns or serious injuries due to fire, electric shock, overheating, or ignition. Charging the headset in this manner can also cause malfunction. Note the following when using the headset while charging.

  • If you feel any abnormalities, stop using the headset immediately.
  • Check that there is no dust or foreign objects in the port.
  • If the USB Type-C cable or USB Type-C port gets wet with liquid such as drinking water or sweat while charging, immediately disconnect the USB Type-C cable from the connected device and stop charging.

Water detection in the charging port

This function is available with headset software version Ver. 2.0.0 or later.
When the headset detects an abnormality, such as water droplets or foreign objects in the USB Type-C port, it will notify you via voice guidance and a notification on the "Sony | Sound Connect" app.
Do not connect the charger while an abnormality is detected.
Note the following.

  • Make sure the USB Type-C port is clear of any foreign objects.
  • If water droplets are present on the charging port, allow it to dry completely before charging.
  • If foreign objects are found in the charging port, carefully remove them with a tool such as an air duster, being careful not to damage the port, and then try charging.

Note

  • The battery does not fully charge when the headset is on.
  • Charging may not be successful with cables other than the supplied USB Type-C cable.
  • The water detection function may malfunction if you use cables other than the supplied USB Type-C cable.
  • Charging may not be successful depending on the type of USB AC adaptor.
  • The headset cannot be charged when the computer goes into standby (sleep) or hibernation mode. In this case, change the computer settings, and start charging once again.
  • If the headset is not used for a long time, the rechargeable battery usage hours may be reduced. However, the battery hours will improve after several charge and discharge cycles. If you store the headset for a long time, charge the battery once every 6 months to avoid over-discharge.
  • If the headset is not used for a long time, it may take longer to charge the battery.
  • If the headset detects a problem while charging due to the following causes, the charging indicator (orange) flashes. In this case, charge once again within the charging temperature range. If the problem persists, consult the Sony support contact or your nearest Sony dealer.
    • Ambient temperature exceeds the charging temperature range of 5 °C - 35 °C (41 °F - 95 °F).
    • There is a problem with the rechargeable battery.
  • If the headset is not used for a long time, the charging indicator (orange) may not immediately light up when the headset starts charging. Please wait a moment until the indicator lights up.
  • If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult the Sony support contact or your nearest Sony dealer.
  • Avoid exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shock. Never leave the headset in a parked vehicle.
  • When connecting the headset to a computer, use only the supplied USB Type-C cable, and make sure to connect them directly. Charging will not be properly completed when the headset is connected through a USB hub.
  • It is not guaranteed that the headset works with all USB PD compatible equipment.
  • When the headset is charged using a USB PD compatible AC adaptor, the right unit may become hot, but this is not a malfunction.
