- Water Resistance: The earphones have an IPX4 waterproof rating, meaning they are resistant to splashing water from any direction. They are suitable for sports and workouts but should not be submerged in water. Dry them thoroughly if they get wet.
- Charging: Use the provided USB Type-C cable and a compatible power adapter for charging. Avoid using damaged cables or chargers.

Troubleshooting
If you encounter any issues with your ERAZER XF50 AI Earphones, please refer to the following common solutions:
- Earphones not pairing: Ensure both earphones are in the charging case, then open the lid to activate pairing mode. Check your device's Bluetooth settings and try re-pairing. Make sure the earphones are charged.
- No sound from one earbud: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often resets the connection.
- Charging issues: Verify that the charging cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
- Translation not working: Confirm that the "Saymi" APP is installed, updated, and properly connected to your earphones. Check your internet connection, as translation features often require online access. Ensure the correct languages are selected in the app.
- Poor sound quality: Check the earbud fit and try adjusting them. Ensure the earphones are within the 10-meter effective range of your connected device.
