Note
Before you use your headphones for the first
time, charge the battery for 2 hours for

Use only the original USB charging cable to
avoid any damage.
Finish your call before charging the
headphones, as connecting the headphones
for charging will power the headphones off.
Connect the supplied USB charging
cable to:
• The USB type C charging slot on the
headphones and;
• The charger/USB port of a
computer.
Tip

earliest paired device is replaced by the
new one.

phone.
