8. Troubleshooting
Common Issues and Solutions:
- Earphones not pairing:
Ensure earphones are charged. Place them back in the case, close, then open again to re-enter pairing mode. Turn off and on your device's Bluetooth. - Only one earphone working:
Try placing both earphones back into the charging case, close the lid, wait a few seconds, then open the lid and take them out again. This often re-syncs them. - Low volume or poor sound quality:
Check the volume level on both your device and the earphones. Ensure the earphones are clean and free of debris. Make sure you are within the effective Bluetooth range (≥ 10 meters). - Earphones not charging:
Ensure the charging cable is securely connected to both the case and the power source. Check if the charging case itself has power. Clean the charging contacts on both the earphones and the case. - Battery life seems short:
Ensure earphones and case are fully charged. High volume usage can reduce battery life.
9. User Tips

The earphones offer about 5 hours of music playtime on a single charge, and the 400mAh charging case can extend this to approximately 18 hours total, allowing for multiple recharges on the go.
- Comfortable Fit: The innovative ear-clip design is meant to provide a secure yet comfortable fit. Experiment with the positioning on your ear to find the most comfortable and stable placement for long listening sessions.
