Cleaning

To maintain optimal performance and hygiene, regularly clean your earbuds and charging case. Use a soft, dry, lint-free cloth. For the eartips, you may gently wipe them with a slightly damp cloth and mild soap, ensuring they are completely dry before reattaching.

Troubleshooting

Common Issues and Solutions

  • Earbuds not pairing: Ensure both earbuds are in the charging case, then remove them. Check your device's Bluetooth settings to ensure it's discoverable and try re-pairing.
  • No sound from one earbud: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open and remove them. This often re-syncs them.
  • Charging issues: Verify the USB-C 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.
  • Poor call quality: Ensure the microphones are not obstructed. Try moving to a quieter environment.
