Troubleshooting
If you cannot connect the headphone to your phone, do as
follows:
Ensure that the headphone is charged and in on state. Ensure
that the Bluetooth feature is activated on your phone. Check
that the headphone is within 10m of your phone and that there
are no obstructions between the headphone and the phone,
such as walls or other electronic devices. The BT-X57 powers
off or does not turn on again could be either a low battery or a
problem with the power supply. Charge the BT-X57 and check
the battery status of the charging box. (We suggest charging
the BT-X57 all 2–3 month if it is not used for a long time.)
