Depending on the settings of various functions and the conditions of use, the speed of the battery consumption may vary
between the left and right units.
As a result, the charging time of the batteries may differ between the left and right units, but this is not a malfunction.
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 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 store the headset for a long time, charge the battery once every 6 months to avoid over-
