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. Set the headset units into the charging case.

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

    When the rechargeable battery of the charging case still has power, the indicator (orange or green) on the charging case lights up for about 3 seconds.

    The charging starts on the headset. Close the charging case lid.

  2. Connect the charging case to an AC outlet.

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

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

    After charging is complete, the indicator on the charging case turns off.

    Remove the USB Type-C cable.

About the charging time

The required time for fully charging the headset and the charging case is about 2 hours*.

*Time required for charging the empty battery to its full capacity. The charging time 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 headset units is about 1.5 hours.

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

This headset is compatible with the wireless chargers that meet the Qi standard. Use a wireless charger that conforms to the Qi standard.

Close the charging case lid and place it on the wireless charger 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 charger.

Hint

  • The headset can be also charged by connecting the charging case to a running computer using the supplied USB Type-C cable.

Note

  • When charging via USB, be sure to use the supplied USB Type-C cable. Using a different cable may prevent charging.
  • Charging may not be successful depending on the type of USB AC adaptor.
  • The left or right headset unit works as the main headset unit, so it consumes the rechargeable battery faster than the other unit. There is a difference in charging time between the left and right headset units, but this is not a malfunction.
    The left or the right headset unit can be the “main headset unit” depending on the usage environment.
  • 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 indicator (orange) on the charging case lights up for about 3 seconds and then turns off when the left and right headset units are removed from the charging case, the remaining battery charge of the charging case is low. Charge the charging case.
  • If the indicator on the charging case does not turn on even when the left and right headset units are removed from the charging case, the battery charge of the charging case is empty. Charge the charging case.
  • 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 charging and discharging several times. 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 charging case lid 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 (orange) on the charging case flashes. When charging wirelessly, charging may slow down or stop at high or low temperatures depending on the wireless charger you are using.
    It is recommended to charge in a place with an ambient temperature between 15 °C and 30 °C (59 °F - 86 °F). Charging outside of this range may result in less efficient charging.
    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.
  • Observe the following precautions when performing wireless charging. Failure to do so may cause fire, burns, injury, or electric shock.
    • Do not attach metallic objects (such as stickers made of materials containing metal) to the wireless charger or the charging case.
    • Remove the cover, etc. attached to the charging case, and do not place metallic objects (such as straps or clips containing metal) on the wireless charger.
    • If something unusual occurs during wireless charging such as unusual odor, unusual sound, smoke, overheating, discoloration, or deformation, carefully and safely remove the charging case from the wireless charger.
  • When you have medical electric devices such as pacemakers or defibrillators implanted, consult your doctor before using the wireless charger. 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 charger. 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 charger to malfunction.
  • When charging wirelessly, charging may slow down or stop if the charging case becomes misaligned with the wireless charger.
  • Depending on the wireless charger you are using, the headset and the charging case may become warm during charging or for a while after charging. However, 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 charger 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 charger. The charging case may not be detected properly and may not be able to charge.
