1. Q: Why can't the headphones pair with my
mobile phone?
A: Please check whether your headphones
are in pairing mode or reconnection mode,
check if the Bluetooth search function of your
Bluetooth device is turned on, then go to the
Bluetooth menu of your Bluetooth device, delete
/forget the headphones and reconnect them.
2. Q: Why can't the headphones turn on?
A: Please double check the battery status of your
headphones.
3. Q: Can I replace the battery in the headphones?
A: No. These headphones use a built-in non-
detachable Li-Polymer battery which can't be
replaced.
4. Q: Can I use the headphones while driving?
A: For your safety, we strongly recommend you do
not use headphones while driving so as to avoid
distraction.
5. Q: Why do the headphones sometimes disc-
onnect from the Bluetooth device within 10 meters?
A: Please check if there is any metal material
within a relatively close range that may be
interfering with the Bluetooth connection. This
may happen because Bluetooth is a radio
technology which is sensitive to objects between
the headphones and the irconnected devices.
