powered on by pressing the power
button.
Solution: Ensure that the headset is
sufficiently charged.
Problem: The mobile phone or
computer cannot be connected to the
Bluetooth headset.
Solution: Follow the correct pairing

operations and ensure that the device to
be paired has the Bluetooth function
enabled.
Problem: The device cannot play
music.
Solution: Ensure that the pairing is
successful.
Problem: A call comes in when I’m
listening to music on the headset. When
I finish the call, the mobile phone cannot
automatically resume music play.
Solution: This should be a system
software issue of the mobile phone. Try
restarting the mobile phone.
Problem: The mobile phone cannot find
the headset through Bluetooth.
Solution:

powered on.

on but still cannot be located, restart

the headset and the mobile phone.
Problem: There is always disconnection
or noises after the headset and a mobile
phone are paired.
Solution:
Ensure that the headset is sufficiently
charged.
Ensure that there is no barrier
between the mobile phone and the
headset that might interrupt signal
transmission.
Ensure that the distance between the
computer or mobile phone and the
headset is within 10 meters.
Problem: The headset is connected
with a mobile phone through Bluetooth,
but I cannot listen to the music.
Solution:
Ensure that both phone audio and
media audio are switched to the
paired headset in the Bluetooth

setting or the player setting on the
mobile phone.
Some mobile phones do not have a
complete stereo Bluetooth module,
hence no function of music play
through a Bluetooth device. You can
connect the headset to other mobile
phones to check if the headset
works.
Problem: Some functions of the player
are not available on the headset.
Solution: Some functions of a player
are not supported by the headset.
Ensure that you use a compatible player
on the mobile phone.
Problem: Slow or no response when

disorder of Bluetooth program caused
by incorrect button operations. Charge
the headset and reset it. Then,

disconnect the charging cable and
power on the headset for re-pairing. The
device should work again.
Problem: Unable to mute the device
using the headset.
Solution: Limited by the Bluetooth
agreement, some devices support the
mute operation on only one device. In
this case, switch the mute function from
the device (mobile phone or computer)
to the headset.
