4. Operating Instructions

- Play/Pause: Single tap on either earbud.
- Next Track: Double tap on the right earbud.
- Previous Track: Double tap on the left earbud.

5. Maintenance
5.1 Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Do not use abrasive cleaners, alcohol, or chemical solvents.
- Ensure charging contacts on both earbuds and case are clean and free of debris for proper charging.
5.2 Water Resistance (IP7)
The earbuds are IP7 waterproof, meaning they are protected against immersion in water up to 1 meter for 30 minutes. This makes them suitable for sports and use in light rain. However, the charging case is not waterproof. Do not submerge the earbuds or expose the charging case to water.
6. Troubleshooting
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode. Check your device's Bluetooth settings.
- Only one earbud working: Place both earbuds back in the charging case, close the lid, then open it again. Ensure both earbuds are taken out simultaneously.
- No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device.
- Charging issues: Clean the charging contacts on both the earbuds and the case. Ensure the charging cable and power source are working correctly.
