Charging the earphones and charging case

The BH410 charging case has an internal, rechargeable battery that must be fully charged before being used for the first time. It takes about 2 hours to fully charge the battery for the first time. If you do not use the device for a long period of time, please charge it once every 2 months to avoid damage to the battery.

• Put the earphones in the charging case and close the cover to charge. During charging, the indicators will show a steady red colour. When the battery is fully charged, the red light will turn off.
  

• Use the USB charging cable to charge the charging case. The indicator light of the charging case is red when being charged. It will turn off automatically after being fully charged.
  

Fully charged earphone batteries have the power for up to 2 hours of playback time (4 hours more from the charging case). When the batteries are running out of power, a voice prompt will be heard. This indicates that the earphones need to be charged as soon as possible.
