Troubleshooting
- No Power:
- Ensure the headphones are fully charged. Connect them to a power source using the charging cable.
- Cannot Pair via Bluetooth:
-
- Make sure the headphones are in pairing mode (LED flashing).
- Ensure Bluetooth is enabled on your device and it's within the <10m range.
- Try restarting both the headphones and your device.
- If previously paired, try forgetting the device on your phone and re-pairing.
- Poor Sound Quality or Disconnections:
-
- Ensure the headphones are within the Bluetooth range of your device.
- Check for interference from other wireless devices.
- Try connecting via the 3.5mm audio cable to rule out Bluetooth issues.
- ANC Performance Issues:
-
- While ANC is effective for general ambient noise, it may not completely isolate human conversations or sharp, irregular sounds.
- Some users have noted "crackling" sounds on bumpy roads, which might be related to micro-vibrations affecting the ANC microphones. This is generally expected behavior for certain types of irregular noise.
