- Driving Safety: Avoid using earphones to listen to music or make/answer calls while driving to prevent distraction and ensure safety.
- Child Safety: Keep the earphones out of reach of children to prevent improper use and potential hazards.
- Physical Damage: Do not throw or drop the product, as this can cause damage.
- Temperature Extremes: Avoid storing or using the headset in environments with temperatures below -20°C or above 45°C, as this can shorten the lifespan of the headset and battery.
- No Disassembly: Do not disassemble, repair, or modify this product yourself. Unauthorized modifications may void the warranty and cause damage.
- Battery Disposal: The battery of this product cannot be replaced by the user. Please dispose of it according to local regulations or hand it over to a professional organization for recycling. Do not dispose of it in fire.
- Long-Term Storage: If the earphones are not used for an extended period, charge them every 3 months to prolong the battery's service life.
7. Troubleshooting
- Earbuds not pairing with each other (TWS): If the left and right earbuds fail to pair automatically, turn both earbuds off by pressing their touch areas for about 5 seconds, then turn them back on. They should then pair automatically.
- Earbuds automatically turning off: If your earphones are disconnected from your mobile device and no operation is performed for 5 minutes, they will automatically turn off to conserve battery. They will also turn off if the distance from the connected device exceeds 10-12 meters and no signal is received for about 5 minutes.
- App connectivity issues: Ensure your phone meets the compatibility requirements (iPhone iOS 10+ or Android 5.0+). If issues persist, try restarting the "Original Sound" App and the earphones, then attempt to reconnect.
- No sound or poor sound quality: Check the earbud fit and try different ear tip sizes. Ensure the earbuds are charged and properly connected to your device. Adjust volume on both the earbuds and your device.
- Charging issues: Ensure the charging cable is securely connected to both the case and a power source. Check if the charging indicator light on the case is active (flashing red when charging, steady red when full). Clean the charging contacts on both the earbuds and the case if necessary.
8. User Tips
- Optimize ANC with Ear Tips: The Realfit F2 Pro comes with two sizes of silicone ear tips. Use the M size for mild noise reduction and comfortable wear, and the L size for deeper noise reduction and better sound isolation. Experiment to find the best fit for your ears and desired noise cancellation level.
Choosing the right ear tip size for optimal ANC performance. - Personalize Your Audio: Utilize the "Original Sound" App to switch between noise reduction, transparency, and game modes. You can also set the EQ mode according to your preferences for a truly personalized audio experience.
- Immersive Gaming: Activate the dedicated Game Mode via the app or touch controls for ultra-low latency (0.06s), ensuring synchronized sound and video for a competitive gaming edge. The 360° stereo sound helps identify in-game locations.
- Extended Playback: With the charging case, enjoy up to 28 hours of total playback. Remember that ANC and Game Mode consume more power, offering 3-4 hours of earbud playback, while Normal Mode provides 5-6 hours.
