③ If 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:
① there may be problems with the sound source itself. Try to switch
to other sound sources.
② The 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.
④ Try 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:
① the Bluetooth connection of the earbud is unstable and there is
interference from other Bluetooth devices, Try to clear other
paired devices.
② When 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.
③ The 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:
① the earbud and charging box have not been used for a long time,
resulting in the power consumption.
② The contact of earbud or charging box is dirty, resulting in
poor contact.
③ The charging cable or charging connector is damaged and
cannot be charged.
④ The earbud charging function fails.
8. Is the earbud voice recognition not sensitive?
Answer:
① accent and pronunciation affect the recognition rate.
② The 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.
