5. Maintenance

5.1. Cleaning

Regular cleaning helps maintain optimal performance and hygiene.

• Wipe the earbuds and charging case with a soft, dry, lint-free cloth.
• Gently remove any earwax or debris from the ear tips and speaker mesh using a clean, dry cotton swab or a small brush.
• Do not use abrasive cleaners or solvents.

5.2. Storage

When not in use, store the earbuds in their charging case to protect them from damage and keep them charged. Store in a cool, dry place away from extreme temperatures.

5.3. IP7 Waterproof Rating

The A90 Pro earbuds are IP7 waterproof, meaning they are protected against sweat and rain. This makes them suitable for workouts and outdoor activities. However, they are not designed for submersion in water.

6. Troubleshooting

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

• Earbuds not pairing:
  Ensure both earbuds are fully charged. Place them back in the charging case, close the lid, then open it again to re-enter pairing mode. On your device, forget the "A90 Pro" from your Bluetooth list and try pairing again.
• No sound or intermittent sound:
  Check the volume levels on both your device and the earbuds. Ensure the earbuds are within the 15-meter Bluetooth range of your device. Try reconnecting the earbuds to your device.
• Charging issues:
  Ensure the USB-C cable is securely connected to both the charging case and the power source. Check if the charging port is clean and free of debris.
• Poor call quality:
  Ensure the earbuds are properly seated in your ears. Move to a quieter environment if possible, as ENC works best to reduce ambient noise but cannot eliminate all background sounds.
