Here are 4 tips for your reference: 1. Clean the contact pins using a clean cloth dipped in alcohol-based disinfectant. Put the cloth on the end of a toothpick for precise cleaning. 2. Clean the metal filter with a dry cotton swab. Remove any debris from the metal filter with a clean, dry, soft-bristled brush. 3. Do not use sharp objects or abrasive materials to clean Liberty 2 Pro. 4. Do not let water get inside Liberty 2 Pro ( the earbuds come with IPX4 protection. In order to protect the electronics inside and ensure the best sound quality, we suggest you wipe away sweat after use and not use in wet conditions. But the charging case isn't waterproof or water resistant, so be careful not to get moisture in any openings.).
