To ensure the longevity and optimal performance of your SGNICS IAII15 Wireless Earbuds, follow these maintenance guidelines:

• Cleaning: Regularly wipe the earbuds and charging case with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
• Water Exposure: While the earbuds and case are IPX7 waterproof, meaning they can withstand submersion up to 1 meter for 30 minutes, it is recommended to dry them thoroughly after exposure to sweat or water before placing them back in the charging case to prevent damage to charging contacts.
• Charging Contacts: If you experience charging issues, gently clean the charging contacts on both the earbuds and inside the charging case with a dry cotton swab.
• Storage: When not in use, store the earbuds in their charging case to protect them from dust and physical damage. Store in a cool, dry place away from extreme temperatures.
