Wireless Noise Canceling Stereo Headset
WH-1000XM4
The available operating time is short (the duration of the battery is short).
When the Equalizer or DSEE Extreme function is used, the available operating time of the headset will be shorter.
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 recharges. If you will store the headset for a long time, charge the battery once
every 6 months to avoid over-discharge.
It is recommended to charge it 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 usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult
your nearest Sony dealer to replace the rechargeable battery.
