Q: Connection is not stable.
A: Bluetooth signal is transmitted wirelessly and signals can be
affected, which results in intermittent sound of earbuds, in
the following conditions:
● The distance between the earbuds and your Bluetooth
device is at the edge of the Bluetooth pairable distance.
● Transmitted signals encounter obstacles or human body
blockage.
● There are high-power electronic devices nearby.
● There are other Bluetooth devices and are being turned
on/off nearby.
To resume stable connection between the earbuds and your
Bluetooth device, try to avoid the above conditions and do
the pairing again following the steps in "Pairing Failed".
Q: Power runs out fast.
A: The earbuds playtime varies according to volume level and
audio content. The following conditions may cause fast
power consumption:
● When the charging case is out of power and you put the
earbuds back into the case, the earbuds will not turn off
automatically. To avoid unwanted power consumption, turn
off the earbuds manually.
● When the earbuds are being charged in the charging case
and the charging case is out of power, the earbuds will
turn on automatically. To avoid unwanted power
consumption, turn off the earbuds manually.
