- Once the second phone is connected, reconnect the first mobile phone to the "S9" headphones. Both devices should now be connected.
Maintenance
General Care and Cleaning
- After each exercise session, especially after swimming or exposure to sweat, wipe off any water or moisture from the surface of the headphones. Pay particular attention to the magnetic charging contacts to prevent corrosion from sweat or saltwater.
- Store the headphones in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid using abrasive cleaners or solvents on the headphones. Use a soft, damp cloth for cleaning.
Battery Care
- If the headphones are not used for an extended period, fully charge them at least once a month to maintain battery health.
- Always use a 5V 1A or 5V 2A charging adapter. Fast chargers are not recommended and can damage the battery.
Swimming and Water Use Precautions
- The S9 headphones are IPX8 waterproof and suitable for use in swimming pools up to 20 meters deep.
- Do not use the headphones for swimming in seawater. Seawater is corrosive to electronic products, and the charging magnetic part can be easily corroded, leading to product damage or malfunction.
- When swimming or using underwater, always switch to "MP3 Music Mode" as Bluetooth signals are absorbed by water and will not connect to your mobile phone.
Troubleshooting
- Headphones not connecting via Bluetooth underwater: This is normal. Bluetooth signals are absorbed by water. Switch to "MP3 Music Mode" for underwater listening.
- Computer not recognizing "S9 U-Disk": Ensure the headphones are properly connected to the computer with the data cable. If it doesn't pop up automatically, manually navigate to "My Computer" (or "This PC") and look for the "S9 U-Disk" drive.
- Charging issues: Ensure you are using a 5V 1A or 5V 2A charger. Check that the magnetic charging cable is securely connected and the contacts are clean and dry.
- Sound leakage: The S9 features DT9.0 directional sound transmission to minimize sound leakage. If you experience significant leakage, ensure the headphones are positioned correctly.
- Headphones falling off during intense activity: The SF-EARS Secure Fit Technology and memory wire ear-hooks are designed for a stable fit. Ensure the ear-hooks are adjusted properly to your ear shape.
