Troubleshooting

If you cannot connect the headphones to your phone:

• Ensure the headphones are charged and powered on.
• Ensure Bluetooth is activated on your phone.
• Check that the headphones are within 10m of your phone and that there are no obstructions (e.g., walls, other electronic devices).

If the BT-X57 powers off unexpectedly or does not turn on:

• This could be due to a low battery or a power supply issue. Charge the BT-X57 and check the charging box's battery status. (We suggest charging the BT-X57 every 2-3 months if not used for extended periods.)

Notes

• Only charge the BT-X57 charging box using the provided USB charging cable and a DC 5V power source. A USB charging adapter can be used, but it must be rated for DC 5V/1A maximum. Do not use higher power adapters.
• If the BT-X57 fails to link to your mobile device or play music after connection, verify that your mobile device supports SBC / ACC audio codecs.
• Noises may indicate a poor Bluetooth signal. Stay within the 10m Bluetooth range to avoid interference.
• Avoid prolonged exposure to excessive volume to prevent noise-induced hearing impairment. Adjust the volume to a comfortable level before wearing the headphones.
