The right/left unit: about 1.5 hours
The charging case: about 3 hours
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 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 remaining battery charge of the charging case is too low, you cannot charge the headset. In this case, the
indicator (red) of the headset flashes and turns off quickly, and then the headset turns off when you set the headset
on the charging case. 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
Charging is also possible by connecting to a booted computer using the supplied micro-USB cable.
If charging starts while the headset is turned on, the headset will turn off automatically.
Note
Charging may not be successful depending on the USB AC adaptor.
If not used for a long time, the duration of the rechargeable battery may be shortened. However, the battery life will improve after
a few recharges.
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.
In this case, charge the headset again.
If the headset detects a problem while charging due to following causes, the indicator (red) may turn off 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.
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 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. Wait for a specified amount of time 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 electrical shock. Never leave the headset in a
parked car.
When connecting to a computer, use the supplied micro-USB cable only, and be sure to connect them directly. Charging will not
be completed properly by an indirect connection, such as via a USB hub.
