Maintenance and Care

• Cleaning: Regularly clean the earbuds and charging case with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
• Ear Tips: Remove ear tips periodically and clean them with mild soap and water. Ensure they are completely dry before reattaching.
• Storage: When not in use, store the earbuds in their charging case to protect them from dust and damage.
• Temperature: Avoid exposing the earbuds to extreme temperatures (hot or cold) or high humidity.
• Material: The earbuds are made from medical-grade, skin-friendly material to minimize allergic reactions. However, if irritation occurs, discontinue use and consult a doctor.

Troubleshooting

• No Sound:
  • Ensure earbuds are charged.
  • Check Bluetooth connection to your device.
  • Adjust volume on both earbuds and your device.
• Earbuds Not Pairing:
  • Place earbuds back in the case, close, then reopen to re-enter pairing mode.
  • Forget the device in your phone's Bluetooth settings and try pairing again.
  • Ensure earbuds are sufficiently charged.
• Noise Cancellation Not Effective:
  • Ensure you have selected the correct ear tip size for a snug fit. A poor seal significantly reduces ANC performance.
  • Verify that Noise Cancellation Mode is activated via touch controls.
• Voice Assistant Not Activating:
  • Ensure you are performing a long-press (3 seconds) on either earbud.
  • Check your phone's settings to ensure voice assistant is enabled and accessible via Bluetooth devices.

User Tips

• Optimal Noise Cancellation: For the best Active and Passive Noise Cancellation performance, ensure you select the correct ear tip size and achieve a tight seal in your ear canal. Experiment with the included S, M, and L tips.
• Mode Switching: Remember that Gaming/Noise Cancellation modes are toggled via the left earbud, while Sleep/Music modes are toggled via the right earbud. This allows for quick adaptation to your environment.
• Side Sleeping Comfort: These earbuds are specifically designed to minimize pressure when lying on your side. If you experience discomfort, double-check the ear tip fit and earbud positioning.
