- Do not use harsh chemicals or abrasive materials for cleaning.
6.2. Storage
- When not in use, the magnetic storage design allows the earbuds to snap together, preventing tangling.
- Store the earbuds in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid placing heavy objects on the earbuds.
6.3. Water Resistance
The earbuds are water-resistant for daily use, making them suitable for workouts and light splashes. However, they are not designed for submersion in water. Avoid prolonged exposure to water or wearing them while swimming.
7. Troubleshooting
If you encounter any issues with your earbuds, please refer to the following common solutions:
- No Power: Ensure the earbuds are fully charged. Connect them to a power source using the Type-C cable.
- Cannot Pair: Make sure the earbuds are in pairing mode (flashing indicator light). Turn off and on your device's Bluetooth, then try pairing again. Ensure the earbuds are not connected to another device.
- No Sound: Check the volume levels on both the earbuds and your connected device. Ensure the earbuds are properly paired.
- Poor Call Quality: Verify that the earbuds are within Bluetooth range of your device. Ensure the microphone is not obstructed. ENC noise reduction works best for environmental noise, not direct voice interference.
- Translation Issues: Ensure your device has a stable internet connection for AI translation features. Check app settings for language selection and microphone permissions.
- Intermittent Connection: Move closer to your connected device to ensure you are within the 10-meter transmission range. Avoid obstacles that may interfere with the Bluetooth signal.
If the problem persists, try resetting the earbuds (refer to the full manual for specific reset instructions) or contact customer support.
