Maintenance
Cleaning
Regularly clean your earbuds and charging case to maintain optimal performance and hygiene. Use a soft, dry, lint-free cloth to wipe the surfaces. For the ear tips, remove them from the earbuds and gently clean with a damp cloth, then allow them to dry completely before reattaching.
Storage
When not in use, store the earbuds in their charging case to protect them and ensure they remain charged. Avoid storing them in extreme temperatures or humid environments.
Troubleshooting
Earbuds Not Pairing
- Ensure the earbuds are charged and removed from the charging case.
- Verify Bluetooth is enabled on your device.
- Try forgetting the device in your Bluetooth settings and re-pairing.
- Place earbuds back in the case, close the lid, wait a few seconds, then open to reset pairing mode.
Low Sound Quality or Volume
- Check that the ear tips are correctly sized and securely fitted in your ears to create a proper seal.
- Clean any debris from the earbud speakers and ear tips.
- Adjust the volume on both your connected device and the earbuds.
- Cycle through the EQ presets to see if a different setting improves sound.
Active Noise Cancellation Not Working Effectively
- Ensure ANC mode is activated (cycle through modes by holding the left earbud for 2 seconds).
- Confirm a tight seal with the correct ear tip size. A poor seal can significantly reduce ANC performance.
