Maintenance

• Cleaning: Regularly clean the earbuds and charging case with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
• Ear Tips: Remove and clean the ear tips periodically with mild soap and water. Ensure they are completely dry before reattaching.
• Storage: When not in use, store the earbuds in their charging case to protect them and keep them charged.
• Water Resistance: The earbuds are water-resistant (sweatproof), making them suitable for sports and exercise. However, they are not designed for submersion in water. Avoid exposing them to excessive moisture.

Troubleshooting

• Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Check your device's Bluetooth settings to ensure "E9" is selected.
• Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This often resets the connection between the two earbuds.
• No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected via Bluetooth.
• Charging issues: Verify that the USB-C cable is securely connected to both the charging case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
