Maintenance
Cleaning
To maintain optimal performance and hygiene, regularly clean your earbuds and charging case. Use a soft, dry, lint-free cloth. Avoid using abrasive materials, solvents, or spray cleaners. Ensure no moisture enters any openings.
Water Resistance
The earbuds are IPX5 compliant, meaning they are resistant to sweat and splashes of water. This makes them suitable for workouts and light rain. However, they are not designed for submersion in water or exposure to pressurized water jets.
Troubleshooting
- No Sound: Ensure earbuds are charged, properly paired, and the volume on both the earbuds and your device is turned up.
- Pairing Issues: Turn off Bluetooth on your device, then turn it back on. Try resetting the earbuds (refer to the quick start guide for specific reset instructions). Ensure no other devices are trying to connect simultaneously.
- Poor Call Quality: Check for obstructions around the microphone. Ensure Environmental Noise Cancellation is active. Move closer to your connected device to improve signal strength.
- Earbuds Not Charging: Verify the USB-C cable is securely connected to both the case and the power source. Check if the charging port is clean and free of debris.
