Maintenance
Water Resistance
The Q18 earbuds have an IP7 waterproof rating, meaning they are protected against immersion in water up to 1 meter for 30 minutes. The surface is sealed to prevent sweat or rain from entering, and an internal nano-coating protects components from moisture damage. While they are waterproof, it is recommended to dry them thoroughly after exposure to water to ensure longevity.

Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Remove eartips and clean any earwax or debris from the mesh screens using a small, soft brush or cotton swab.
- Ensure charging contacts on both earbuds and case are clean and dry for optimal charging.
Troubleshooting
Connectivity Issues
- Earbuds not pairing: Ensure both earbuds are removed from the charging case. Turn off and on your device's Bluetooth, then try pairing again.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then remove them. This should reset their connection.
- Unstable connection: Ensure you are within the 15-meter Bluetooth range of your device. Avoid obstacles that may interfere with the signal.
Sound Issues
- No sound: Check the volume level on both your device and the earbuds. Ensure earbuds are properly seated in your ears.
- Low sound quality: Ensure eartips are the correct size for a snug fit. Clean any debris from the earbud speakers.
Charging Issues
- Earbuds not charging: Ensure the charging contacts on both the earbuds and inside the case are clean and dry. Check if the charging case itself has sufficient battery.
- Charging case not charging: Ensure the USB-C cable is securely connected to both the case and the power source. Try a different cable or power adapter.
