Troubleshooting
- Earphones not pairing: Ensure earphones are charged and in pairing mode. Turn off and on Bluetooth on your device. Forget the device in Bluetooth settings and try pairing again.
- Only one earphone working: Place both earphones back in the charging case, close the lid, wait a few seconds, then open and try again. Ensure both earphones have sufficient charge.
- Poor sound quality: Check if the ear tips are properly sealed in your ear. Try different sized ear tips. Ensure your device is within Bluetooth range and there are no obstructions.
- ANC not working effectively: Ensure earphones are properly seated in your ears. Toggle ANC modes using the touch controls.
- Charging issues: Ensure the charging cable is securely connected to both the case and a power source. Clean the charging contacts on both the earphones and the case.
User Tips
Based on general user feedback for similar products, here are some tips:
- Find the Right Fit: Experiment with the included ear tips to find the size that provides the best seal for optimal sound quality and noise cancellation. A good seal is crucial for bass response and effective ANC.
- Regular Cleaning: Clean the ear tips and earphone grilles regularly to prevent wax buildup, which can affect sound quality and volume.
- Firmware Updates: Check the official VIVO app (if available) for any firmware updates, as these can improve performance, stability, and add new features.
- Optimize 3D Audio: For the best 3D panoramic audio experience, ensure your device meets the specified compatibility requirements (Android 13+, MTK/Qualcomm, 6GB+ RAM).
Maintenance
To ensure the longevity and optimal performance of your VIVO TWS 4 earphones:
- Cleaning: Use a soft, dry, lint-free cloth to clean the earphones and charging case. For ear tips, you can gently wipe them with a damp cloth and mild soap, then rinse and dry thoroughly before reattaching.
- Water Resistance: The earphones are IP54 waterproof, meaning they are protected against dust and splashing water. However, it is recommended to avoid using them during strenuous exercise or in highly humid environments to prevent damage from sweat infiltration. Do not submerge them in water.
- Storage: Store the earphones in their charging case when not in use to protect them from dust and physical damage. Keep them in a cool, dry place away from extreme temperatures.
- Avoid Harsh Chemicals: Do not use alcohol, benzene, or other volatile liquids to clean the product.
