Operation

• Carefully insert the earbud into the ear

canal and make sure it does not fall out if 
you shake your head. 

• When receiving a call, slightly touch the

earbud or use your phone directly to 
answer the call.

• When receiving a call, touch and hold

the earbud for two seconds to refuse 
the call. 

• Gently touch the earbud to play and 

pause music.

• Touch the left earbud three times

to go to the previous track. Touch the right 
earbud three times to go to the next track.

• Pairing is required once per device. If

you want to pair the earbuds with a new 
device, switch them off and unpair from the 
existing device, then repeat the above steps 
with a new device.

• The wireless range is approximately

within 10 meters in direct line of sight.

Charging

•

Before using the device, fully charge the 

earbuds and the charging case. To do so, 
insert the earbuds into the L (left) and R 
(right) slots inside the case. Charging will 
start automatically.

•

Plug the USB cable into the power adapter 

and into the device (power adapter not 
included) for charging, to charge the earbuds 
and the charging case at the same time.

•

The LEDs on the charging case will flash in 

blue

 and stop flashing when fully charged.

Switching on/off

•

Switch on: The earbuds are switched on 

automatically when you take them out of the 
charging case.

•

Switch off: Touch the earbud and hold for 

3-5 seconds to switch it off. Alternatively, you 
can put it in the charging case after which it 
will also switch off. The earbuds will also 
switch off when your bluetooth device is out 
of range longer than 5 minutes.

•

When the two earbuds are paired (TWS 

mode), they can switch off at the same time. 

       Interruption of sound transmission is 
not a defect in the earbuds, but may 
happen due to the loss of a signal from the 
control device.

• For iOS devices: touch and hold the 

earbud to activate Siri.

Bluetooth pairing

and take out the earbuds, they will pair with
