Maintenance
Cleaning
Regularly clean your earbuds and charging case to maintain optimal performance and hygiene. Use a soft, dry, lint-free cloth. For ear tips, remove them and gently wipe with a damp cloth, then dry thoroughly before reattaching. Do not use harsh chemicals or abrasive materials.
Sweat and Water Resistance (IPX5)
The earbuds are IPX5 sweat and weather resistant, meaning they can withstand sweat and light splashes of water. They are not designed for submersion in water. Ensure the charging port is dry before charging to prevent damage.

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.
Troubleshooting
| Problem | Possible Solution |
|---|---|
| Earbuds not turning on | Ensure earbuds are charged. Place them in the charging case for a few minutes, then remove. |
| Earbuds not pairing | Make sure Bluetooth is enabled on your device. Forget the device in your Bluetooth settings and try pairing again. Ensure earbuds are out of the case and in pairing mode. |
| Only one earbud working | Place both earbuds back in the charging case, close the lid, wait a few seconds, then remove them simultaneously. This often re-syncs them. |
| No sound or low volume | Check the volume level on both your device and the earbuds. Ensure earbuds are properly connected. Clean any debris from the earbud speakers. |
| Charging issues | Ensure the charging cable is securely connected to both the case and the power source. Try a different USB port or cable. Clean the charging contacts on the earbuds and inside the case. |
