About charging

The charging case: about 3 hours

Charging the headset when you are outside

A rechargeable battery is built in the charging case. If you charge the charging case in advance, you can charge the headset with it when you are outside where there is no power supply.
If the charging case is charged fully, you can charge the headset about 2 times.


Notes on charging the headset when you are outside

  • If the indicator (red) flashes and then turns off quickly when you set the headset on the charging case, you cannot charge the headset because the remaining power of the rechargeable battery (which is built in the charging case) is low. To turn on the headset, remove it from the charging case and then press and hold the buttons both on the right and left unit for about 2 seconds until the indicator (blue) flashes.
  • If the indicator (red) does not light up/flash and the headset does not turn off even when you set the headset on the charging case, the remaining power of the rechargeable battery (which is built in the charging case) is empty. To turn off the headset, remove it from the charging case and then press and hold the button on the left unit for about 2 seconds until the indicator (blue) flashes. The left unit and right unit turn off.

Hint

  • If charging starts while the headset is turned on, the headset will turn off automatically.

Note

  • If the headset is not used for a long time, the battery may be quickly depleted, however, after a few recharges, the battery life will improve.
  • If you store the headset for a long time, charge the battery to its full capacity 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 computer enters into hibernation mode while connected to the headset, charging will not be completed properly. Check the setting of the computer before charging. The indicator (red) will go off automatically if the computer enters into hibernation mode. Charge the headset again in this case.
  • If the headset detects a problem while charging due to following causes, the indicator (red) of the headset may turn off or the indicator (red) of the charging case may flash, although charging is not complete. In this case, charge again within the charging temperature range. If the problem persists, consult 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 battery.
  • If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset: wait a few minutes until the indicator (red) lights up.
  • If the life of the built-in rechargeable battery drops significantly, the battery should be replaced. Consult your nearest Sony dealer for replacement of the rechargeable battery.
  • Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave the headset in a car parked in the sun.
  • Use the supplied micro-USB cable only, and connect directly to a computer. Charging will not be completed properly by an indirect connection, such as via a USB hub.
