Charging

The headset and the charging case contain built-in lithium-ion rechargeable batteries. Use the supplied USB Type-C cable to charge the headset before use.

  1. Remove the headset and pull the insulating sheet out of the charging case.

    Dispose of the removed insulating sheet.

  2. Set the headset into the charging case.

    Put the left unit of the headset (the unit with the tactile dot) back into the left hole of the charging case, and put the right unit of the headset back into the right hole of the charging case. Each unit of the headset will be set to the correct position in the charging case by the built-in magnet.

    Close the lid of the charging case after setting the headset into the charging case.


  3. Connect the charging case to an AC outlet.

    Use the supplied USB Type-C cable and a commercially available USB AC adaptor.

    The indicator (orange) on the charging case lights up, and charging starts on the headset and the charging case.

    When charging of the headset and the charging case is complete, the indicator (orange) on the charging case turns off automatically. Remove the USB Type-C cable.

About the charging time

The required time for fully charging the headset and the charging case is about 3 hours (*).

*Time required for charging the empty battery to its full capacity. It may differ depending on the conditions of use.

Charging the headset when you are outside

A rechargeable battery is built into the charging case. If you charge the charging case in advance, you can use it to charge the headset when you go out without a power supply.

The required time for fully charging the left and right units of the headset is about 1.5 hours.


Notes on charging the headset when you are outside

When the headset is removed from the charging case, if the indicator (orange) on the charging case lights up, the remaining battery charge of the charging case is low. If the indicator does not light up, the battery charge of the charging case is empty. Charge the charging case.

System requirements for battery charge using USB

USB AC adaptor

A commercially available USB AC adaptor capable of supplying an output current of 0.5 A (500 mA) or more

Personal computer

Personal computer with a standard USB port

  • We do not guarantee operation on all computers.
  • Operations using a custom-built or homebuilt computer are not guaranteed.

Wireless charging

Wireless charging is available using a commercially available wireless charging pad that meets the Qi standard.

Close the lid of the charging case and place it on the wireless charging pad with the SONY logo of the charging case facing upward to charge.

See “Location and function of parts” for the location of the charging contact surface.
When charging, refer to the operating instructions supplied with the wireless charging pad.

Hint

  • The headset can be also charged by connecting the charging case to a running computer using the supplied USB Type-C cable.
  • When you put the headset units into your ears, the voice guidance indicating the remaining battery charge can be heard. The remaining battery charge indicated by the voice guidance may differ from the actual remaining charge in some cases. Use it as a rough estimate.

Note

  • Charging may not be successful with cables other than the supplied USB Type-C cable.
  • Charging may not be successful depending on the type of USB AC adaptor.
  • Depending on the settings of various functions and the conditions of use, the speed of the battery consumption may vary between the left and right units.
    As a result, the charging time of the batteries may differ between the left and right units, but this is not a malfunction.
  • 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 life will improve after a few charges and discharges. 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.
  • Be sure to close the lid of the charging case to prevent the battery of the charging case from being consumed.
  • If there is a problem with the rechargeable battery of the headset or the charging case and something unusual is detected during charging, the indicator (red) on the charging case flashes. When charging wirelessly, charging may slow down or stop at high or low temperatures depending on the wireless charging pad you are using.
    It is recommended to charge in a place with an ambient temperature between 15 °C and 35 °C (59 °F - 95 °F). Efficient charging may not be possible beyond this range.
    If the problem persists, consult your nearest Sony dealer.
  • If the headset is not used for a long time, the indicator (orange) on the charging case may not immediately light up when charging. Wait a moment until the indicator (orange) lights up.
  • If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult 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 charging case to a computer, use only the supplied USB Type-C cable, and be sure to directly connect them. Charging will not be properly completed when the charging case is connected through a USB hub.
  • Do not attach metallic objects (such as stickers made from material containing metal) on the wireless charging pad or the charging case. Doing so may cause fires, burns, or injuries.
  • When using the wireless charging pad, do not place metallic objects (such as straps or clips made from material containing metal) on the wireless charging pad. Doing so may cause fires, burns, or injuries.
  • When charging with the wireless charging pad, remove the parts such as covers attached to the charging case. Depending on the material or thickness of the cover, or due to foreign objects caught between the charging case and the cover, charging may not be performed properly, resulting in fires, burns, or injuries.
  • When you have medical electric devices such as pacemakers or defibrillators implanted, consult your doctor before using the wireless charging pad. Radio waves may affect the operations of the medical electric devices.
  • Do not bring IC cards, magnetic cards, or magnetized objects close to the wireless charging pad. Doing so may cause IC cards to malfunction. Magnetic data may be erased from cash cards, credit cards, telephone cards, or floppy disks. When strong magnetism is brought close by, it may cause the wireless charging pad to malfunction.
  • When charging wirelessly, charging may slow down or stop if the charging case becomes misaligned with the wireless charging pad.
  • When charging wirelessly, charging may slow down or stop at high or low temperatures depending on the wireless charging pad you are using.
  • Depending on the wireless charging pad you are using, the headset and the charging case may become warm during charging or for a while after charging, but this is not a malfunction.
  • Do not charge the headset wirelessly in the following locations.
    • Where the headset is subject to high levels of humidity, dust or vibration, or near telephones, TVs, radios, etc.
  • Do not use the wireless charging pad when it is covered by a blanket, etc.
  • When noise is heard from the TV or radio while the headset is under wireless charging, charge the headset at a location away from the TV or radio.
  • When charging wirelessly, if there are other devices compatible with wireless charging nearby, move the devices 30 cm (11.81 in.) or more away from the wireless charging pad. The charging case may not be detected correctly, and charging may not be performed.
