Before using any USB charger to charge this earbud,
check whether the specifications of the charger meet requirements. The
suggested output current is 100mA to 500mA. An over-high charging
voltage may damage the earbud.
1. If the red indicator on the earbud blinks, and a prompt tone “Low battery,
please charge” is heard, it’s indicated the earbud battery is low. If the earbud
continues to work, it will automatically power off when the battery runs out.
Then, you need to charge the earbud by connecting the cable of the charger
to the charging port on the earbud.
2. Connect the charger to an AC power socket.
3. The red indicator is on when the earbud is being charged. If the charging is
not started yet, disconnect the earbud from the power socket, and reconnect
the earbud again. It takes about 2 hours to fully charge the earbud. The red
indicator will return off automatically after fully charged. Then, you can
disconnect the charger from the power socket and earbud.
4. A full charged battery can provide about 3.5 hours of talking time, or about
80 hours of standby time. The actual talk time and standby time may vary
from different smartphones, mobile devices, settings, using scenario, and
environments etc.
Only use the suggested charger if possible. Other chargers may
violate the warranty terms of the equipment and results in danger. IF the
charging cable is delivered with the earbud, connect the cable to a certified
charger or computer to charge the earbud.
The earbud includes an internal non-removable charging battery. Do not
remove the battery from the earbud; otherwise, the earbud may be
damaged. If the earbud is not used in a long time, keep it in a dry and
well-ventilated place, and charge the earbud once a month.
