- Ensure charging contacts on both earbuds and case are clean and free of debris for optimal charging.
6.2 Water Resistance (IP7)
The earbuds are rated IP7 waterproof, meaning they are protected against temporary immersion in water up to 1 meter for 30 minutes. This makes them suitable for workouts and use in light rain. However, they are not designed for swimming or prolonged water exposure. The charging case is not waterproof.

7. 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 and try reconnecting.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This should reset the connection and allow them to pair with each other. If the issue persists, try resetting the earbuds (refer to manufacturer's specific reset instructions if available, or try forgetting the device on your phone and re-pairing).
- Earbuds not charging: Ensure the charging cable is securely connected to both the case and the power source. Check that the charging contacts on the earbuds and inside the case are clean and free of obstructions.
- Low volume or poor sound quality: Adjust the volume on both your device and the earbuds. Ensure the earbuds are properly seated in your ears. Clean any earwax or debris from the earbud speakers.
- Connectivity issues: Ensure your device is within the Bluetooth range (up to 15 meters). Avoid obstacles between your device and the earbuds. Try disconnecting and reconnecting the Bluetooth connection on your device.
