8. Maintenance and Care
8.1 Water Resistance (IP55)
The earbud bodies are rated IP55 for dust and water resistance. This means they are protected against limited dust ingress and low-pressure water jets from any direction. However, this rating does NOT apply to the charging case. It is recommended to avoid using the earbuds during strenuous exercise where excessive sweat may occur, as sweat infiltration can cause damage. The dust-proof and waterproof functions are not permanently effective and may decrease over time due to daily wear and tear.
Important: Do not charge the earphones in a humid state. Always dry the earphones thoroughly after use if they have residual sweat or rain on them. Damage caused by immersion in liquid is not covered by the warranty.
8.2 Cleaning
- Gently wipe the earbuds and charging case with a soft, dry, lint-free cloth.
- Avoid using abrasive materials, solvents, or chemical cleaners.
- Ensure charging contacts are clean and dry before charging.
9. Troubleshooting
9.1 Pairing Issues
If you experience difficulty pairing your earbuds or connecting to a new device:
- Place both earbuds in the charging case and ensure the case is open.
- Press and hold the function button at the bottom of the charging case for 2 seconds until the white indicator light flashes. This resets the earbuds and puts them into pairing mode.
- On your device, forget any previous "OPPO Enco R3 Pro" Bluetooth connections.
- Search for and select "OPPO Enco R3 Pro" in your device's Bluetooth settings to re-pair.
- Ensure your device's Bluetooth is enabled and within range (within 10m).
9.2 Sound Quality Issues
- Ensure the earbuds are clean and free from debris.
- Try different sizes of ear tips to ensure a proper seal in your ear canal.
- Check the audio source device for any issues.
9.3 Battery Life Concerns
- Ensure both earbuds and the charging case are fully charged.
- Note that Active Noise Cancellation (ANC) and LHDC 5.0 codec usage will reduce overall battery life.
- Battery performance may vary based on volume level and usage patterns.
10. User Tips
- Optimal Noise Reduction: The 49dB noise reduction depth is a maximum value from lab tests. Actual performance can vary based on ear shape, ear tip size, wearing position, and ambient noise. Experiment with different ear tip sizes for the best seal.
- LHDC 5.0 Transmission: To fully utilize the LHDC 5.0 ultra-clear transmission protocol (up to 1Mbps), ensure both your earbuds and the connected device (OPPO/Oneplus mobile phones with ColorOS 13.1+ or specific Find/Reno/Oneplus series) support LHDC transmission.
- Battery Life: The stated battery life of 44 hours (with case, ANC off, AAC, 50% volume) is based on lab conditions. Real-world usage may differ.
- Spatial Sound: The spatial sound function requires compatible OPPO and Oneplus mobile phones (e.g., Find X8 series, Find X6 Pro, Find X7, Find X7 Ultra, Reno 13 series, Find N3, Find N3 Flip, Oneplus 11, 12, 13, Ace series).
11. Warranty and Support
