Maintenance

Cleaning

To maintain optimal performance and hygiene, regularly clean your earbuds and charging case.

• Gently wipe the earbuds and charging case with a soft, dry, lint-free cloth.
• Clean both charging contacts of the earbuds and the charger seat regularly. Remove any sweat, perspiration, or dirt to prevent charging failures.
• Remove eartips and clean them with mild soap and water, then dry thoroughly before reattaching.

Storage

Troubleshooting

If you encounter any issues with your OYIB S75 Wireless Earbuds, refer to the following common solutions:

• Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid. Check your device's Bluetooth settings to ensure it's searching for new devices. If issues persist, try forgetting the device on your phone and re-pairing.
• No sound from one earbud: Place both earbuds back into the charging case, close the lid, and then open it again. This often re-syncs them.
• Charging issues: Clean the charging contacts on both the earbuds and inside the case. Ensure the USB-C cable is securely connected and the power source is active.
• Low volume/poor sound quality: Adjust the volume on both your device and the earbuds. Ensure the eartips are the correct size and provide a good seal in your ear canal.
• Earbuds falling out: Experiment with different eartip sizes to find the best fit. Ensure the over-ear hooks are properly positioned and adjusted.
