Troubleshooting
If you encounter issues with your SUUNTO Sonic headphones, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cannot connect via Bluetooth | Headphones not in pairing mode; device Bluetooth off; interference; previous connection issues. | Ensure headphones are in pairing mode. Turn off and on Bluetooth on your device. Forget "SUUNTO Sonic" from your device's Bluetooth list and re-pair. Try connecting in a different environment to rule out interference. |
| Low volume or poor sound quality | Volume too low on headphones or device; improper placement; environmental noise. | Increase volume on both headphones and connected device. Ensure transducers are correctly placed on cheekbones. Note that open-ear design allows ambient sound, which may affect perceived loudness in noisy environments. |
| Headphones do not charge | Charging cable or port issue; power source problem. | Check if the charging cable is securely connected. Try a different USB port or power adapter. Ensure the charging port on the headphones is clean and dry. |
| Uncomfortable fit / too big | Individual head size variation. | While designed for a secure fit, individual comfort may vary. Ensure the band is positioned correctly around the back of the head. |
