1. Does the earbud not turn on?

Answer:

① check whether the earbud has no power, and charge the earbud

in time.

2. Is the earbud signal unstable?

Answer:

① restart the earbud (put it back into the charging box and pick it

up again).

② Check the compatibility and call quality of the mobile phone.

③ Conﬁrm whether the connected device is too far away from the

earbud or there is interference in the surrounding environment.

④ Do not stay in the environment of signal interference reflection.

3. Why is the single / dual earbuds suddenly silent during use?

Answer:

① the Bluetooth switch of the mobile phone is touched by mistake

and the Bluetooth of the mobile phone is turned off.

②Due to the particularity of Bluetooth earbuds, your area is in the

environment with strong electromagnetic interference, and it will

be silent.

③Whether the earbud is set to mute mode.

4. What if there is an electric current sound in the ear?

Answer:

① if the current sound is obvious, please conﬁrm whether it is

caused by environmental interference. It is suggested to use or

close the WiFi equipment at another place to reduce interference.

② Please try to put the earbud back into the charging box, close the

box cover for 5 seconds, open the box cover and reconnect with

the phone to conﬁrm whether the current sound disappears or

attenuates. Or after hard reset and restart, connect the mobile

phone to conﬁrm whether the current sound disappears or

attenuates.

FREQUENTLY ASKED QUESTION ③If there is a slight bottom noise current sound, it is mainly caused

by the interference of wireless signals (such as Bluetooth, WiFi

and GPS) in the environment during Bluetooth communication.

5. What is the difference between the left and right earbud?

Answer:

①there may be problems with the sound source itself. Try to switch

to other sound sources.

②The earbud accidentally enters water, and the water drops gather

on the surface of the horn diaphragm, which may cause the

sound to become small. In this case, please place the earbud for

a period of time in a ventilated and sufﬁcient sunshine

environment to fully remove the water in the earbud.

③ If the sound outlet of the earbud head is blocked by dirt, the

sound will be reduced. In this case, please remove the dirt.

④Try to replace the ear tips. The size of the ear tips will also affect

the sound perception.

6. Is there a noise in the earbud when answering the phone?

Answer:

①the Bluetooth connection of the earbud is unstable and there is

interference from other Bluetooth devices, Try to clear other

paired devices.

②When the earbud is far away from the mobile phone, or when

there is a shield between the earbud and the mobile phone, the

Bluetooth communication quality will be poor and noise may be

generated. Move the mobile phone close to the earbud and

remove the shield.

③The environmental electromagnetic interference is large, which

affects the communication between the earbud and the mobile

phone, and may cause the noise of the call.

7. What if the earbud cannot be charged?

Answer:

①the earbud and charging box have not been used for a long time,

resulting in the power consumption.

②The contact of earbud or charging box is dirty, resulting in

poor contact.

③The charging cable or charging connector is damaged and

cannot be charged.

④The earbud charging function fails.

8. Is the earbud voice recognition not sensitive?

Answer:

①accent and pronunciation affect the recognition rate.

②The noise of the surrounding environment affects the

recognition rate.

③ Speak too fast or too slowly.

④ The earbud is not properly worn and does not ﬁt the ear well.

1. Does the earbud not turn on?

Answer:

① check whether the earbud has no power, and charge the earbud

in time.

2. Is the earbud signal unstable?

Answer:

① restart the earbud (put it back into the charging box and pick it

up again).

② Check the compatibility and call quality of the mobile phone.

③ Conﬁrm whether the connected device is too far away from the

earbud or there is interference in the surrounding environment.

④ Do not stay in the environment of signal interference reflection.

3. Why is the single / dual earbuds suddenly silent during use?

Answer:

① the Bluetooth switch of the mobile phone is touched by mistake

and the Bluetooth of the mobile phone is turned off.

②Due to the particularity of Bluetooth earbuds, your area is in the

environment with strong electromagnetic interference, and it will

be silent.

③Whether the earbud is set to mute mode.

4. What if there is an electric current sound in the ear?

Answer:

① if the current sound is obvious, please conﬁrm whether it is

caused by environmental interference. It is suggested to use or

close the WiFi equipment at another place to reduce interference.

② Please try to put the earbud back into the charging box, close the

box cover for 5 seconds, open the box cover and reconnect with

the phone to conﬁrm whether the current sound disappears or

attenuates. Or after hard reset and restart, connect the mobile

phone to conﬁrm whether the current sound disappears or

attenuates.

FREQUENTLY ASKED QUESTION ③If there is a slight bottom noise current sound, it is mainly caused

by the interference of wireless signals (such as Bluetooth, WiFi

and GPS) in the environment during Bluetooth communication.

5. What is the difference between the left and right earbud?

Answer:

①there may be problems with the sound source itself. Try to switch

to other sound sources.

②The earbud accidentally enters water, and the water drops gather

on the surface of the horn diaphragm, which may cause the

sound to become small. In this case, please place the earbud for

a period of time in a ventilated and sufﬁcient sunshine

environment to fully remove the water in the earbud.

③ If the sound outlet of the earbud head is blocked by dirt, the

sound will be reduced. In this case, please remove the dirt.

④Try to replace the ear tips. The size of the ear tips will also affect

the sound perception.

6. Is there a noise in the earbud when answering the phone?

Answer:

①the Bluetooth connection of the earbud is unstable and there is

interference from other Bluetooth devices, Try to clear other

paired devices.

②When the earbud is far away from the mobile phone, or when

there is a shield between the earbud and the mobile phone, the

Bluetooth communication quality will be poor and noise may be

generated. Move the mobile phone close to the earbud and

remove the shield.

③The environmental electromagnetic interference is large, which

affects the communication between the earbud and the mobile

phone, and may cause the noise of the call.

7. What if the earbud cannot be charged?

Answer:

①the earbud and charging box have not been used for a long time,

resulting in the power consumption.

②The contact of earbud or charging box is dirty, resulting in

poor contact.

③The charging cable or charging connector is damaged and

cannot be charged.

④The earbud charging function fails.

8. Is the earbud voice recognition not sensitive?

Answer:

①accent and pronunciation affect the recognition rate.

②The noise of the surrounding environment affects the

recognition rate.

③ Speak too fast or too slowly.

④ The earbud is not properly worn and does not ﬁt the ear well.
