5. Maintenance

To ensure the longevity and optimal performance of your HTC TWS12 earbuds, follow these maintenance guidelines:

• Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Avoid using abrasive materials or harsh chemicals.
• Eartips: Remove and clean the eartips periodically with water and mild soap. Ensure they are completely dry before reattaching.
• Water Resistance: The earbuds are waterproof. While they can withstand splashes and sweat, avoid submerging them in water for extended periods. Ensure the charging port is dry before charging.
• Storage: When not in use, store the earbuds in their charging case to protect them and keep them charged.
• Temperature: Avoid exposing the earbuds to extreme temperatures (hot or cold) or direct sunlight.

6. Troubleshooting

If you encounter any issues with your HTC TWS12 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. Turn off and on your device's Bluetooth, then try searching again.
• Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often resets the connection.
• No sound: Check the volume level on your connected device and on the earbuds. Ensure the earbuds are properly paired and selected as the audio output device.
• Charging issues: Verify the USB-C cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
• Poor sound quality: Ensure the eartips provide a good seal in your ear. Try different eartip sizes. Move closer to your connected device to avoid interference.
