4. Maintenance
4.1 Cleaning
- Gently wipe the earbuds and charging case with a soft, dry, lint-free cloth.
- Remove ear tips and clean them separately with mild soap and water if necessary. Ensure they are completely dry before reattaching.
- Avoid using abrasive materials, solvents, or harsh chemicals.
4.2 Water Resistance (IPX7)
The earbuds are rated IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This protects against sweat, rain, and accidental splashes. However, they are not designed for swimming or prolonged submersion.
- Do not charge the earbuds or case if they are wet.
- Ensure the charging port is dry before connecting the USB-C cable.
4.3 Storage
When not in use, store the earbuds in their charging case to protect them and keep them charged. Store in a cool, dry place away from extreme temperatures.
5. Troubleshooting
5.1 Connectivity Issues
- Earbuds not pairing: Ensure both earbuds are in the charging case, close the lid, then open it again to re-enter pairing mode. Check your device's Bluetooth settings to ensure it's discoverable.
- Intermittent connection: Ensure the earbuds are within the 10-meter Bluetooth range of your device. Avoid obstacles that may interfere with the signal.
- Only one earbud connecting: Place both earbuds back in the case, close the lid, and then open it again. If the issue persists, try resetting the earbuds (refer to the full user manual for specific reset instructions if available).
5.2 Charging Issues
- Earbuds not charging: Ensure the earbuds are correctly seated in the charging case. Check that the charging pins on the earbuds and in the case are clean and free of debris.
- Case not charging: Verify the USB-C cable is securely connected to both the case and the power source. Try a different USB-C cable or power adapter.
5.3 Sound Quality Issues
- Low volume or poor sound: Adjust the volume on both your device and the earbuds. Ensure the ear tips provide a snug seal in your ear canal. Try different sized ear tips.
- Distorted audio: Move closer to your connected device. Check if any EQ modes are active that might be affecting the sound.
5.4 Sleep Mode Behavior
- Sleep mode not activating/deactivating: Ensure both earbuds are in use. Remember that sleep mode is not available for single-ear use.
- Notifications still heard in sleep mode: Verify that sleep mode is fully engaged via the charging case touch screen or earbud controls.
