battery life will improve after charging and discharging several times. If you store the headset for a long time, charge

the battery once every 6 months to avoid over-discharge.

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 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.
