5. Maintenance

To ensure the longevity and optimal performance of your Jzones U7 earbuds, follow these maintenance guidelines:

• Cleaning: After each use, especially after workouts, use a soft, dry cloth (a cleaning cloth is included in the box) to gently wipe any dirt or sweat from the earbuds and charging case. Ensure the charging contacts are clean.
• Water Resistance: The earbuds are IPX7 waterproof, meaning they are protected against immersion in water up to 1 meter for up to 30 minutes. However, they are not designed for swimming or prolonged submersion. Always ensure the earbuds are dry before placing them back into the charging case to prevent damage.
• Storage: Store the earbuds in their charging case when not in use to protect them from dust, damage, and to keep them charged.

6. Troubleshooting

If you encounter any issues with your Jzones U7 earbuds, please refer to the following common solutions:

• 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 "U7" is selected. If issues persist, try forgetting the device on your phone and re-pairing.
• Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This often re-syncs them. Ensure both earbuds have sufficient charge.
• Charging case not charging: Verify the Type-C cable is securely connected to both the case and the power source. If using wireless charging, ensure the case is correctly positioned on the charging pad. Check if the power source is active.
• Low volume or poor sound quality: Adjust the volume on both your device and the earbuds. Ensure the ear caps are properly fitted and clean. Try different ear cap sizes for a better seal.
• Connectivity issues: Ensure your device is within the 10-meter Bluetooth range. Avoid obstacles between your device and the earbuds that might interfere with the signal.
