The wireless headset cannot be charged or does not turn on.

    Please check the following and see if the condition improves.

    • Set the headset in the charging case and close the lid.

      Insert both sides of the headset into the charging case connected with the USB cable, then check that the headset indicator (red) lights up.
      If the indicator does not light up, close the lid and wait about 30 seconds. Then open the lid and check that the indicator (red) on the headset is lit.

    • Reset the headset

      1. Place the headset in the charging case, leave the lid of the charging case open, then hold your finger to the touch sensor on the left unit for about 20 seconds.

      2. Release your finger when the indicator (red) of the headset turns off after flashing.
        NOTES: 

        • If the indicator (red) did not flash in Step 1, you may need to hold your finger to the touch sensor on the left side of the headset for about 30 seconds.
        • You may be able to continue even if the indicator (red) does not flash.
      3. Hold your finger to the touch sensor on the right unit for about 20 seconds.

      4. Release your finger when the indicator (red) of the headset turns off after flashing.
        NOTES:

        • You may be able to continue even if the indicator (red) does not flash.
      5. Check to see if the issue is resolved after resetting.
        NOTE: The red indicator light may be lit after the reset is finished.

      NOTES:
    • Charge the charging case with the supplied USB Type-C cable.

      The below conditions appear when the remaining power in the rechargeable battery of the charging case is low, and the headset cannot be charged.

      • When the headset’s indicator (red) lights up and immediately turns off, and the headset power turns off when the headset is set to the charging case.
      • When the headset indicator (red) doesn’t light up on and the headset power doesn’t turn off even if the headset is set to the charging case.
    • Wipe the terminal of the headset and charging case with a dry soft cloth (such as those for commercial glasses).

      If the terminal is dirty, charging may not be possible.
      It is recommended to regularly clean the terminal.

    • Charge in an environment at 5°C - 35°C (41°F - 95°F).

      If the temperature is too low or high, charging may not be possible.
      It is recommended to charge the headset in an environment with an ambient temperature range of 15°C and 35°C (59°F - 95°F) for efficient charging.
