Regular cleaning can prolong the service life of the product. If not used for a long time, it is recommended to charge once every �� days to extend the battery life. The surfaces of the charging pads on the earbud stem should be regularly wiped with cotton swabs and alcohol to help smooth charging, avoid poor contact, and affect the user experience. Batteries (battery packs or combinations of cells) must not be exposed to lighting, baking, or similar excessive heat. It is forbidden to disassemble, impact, crush or throw into fire. If severe swelling occurs, do not continue to use. Never leave in a high temperature environment. It is forbidden to use after immersion in water. Since this product adopts wireless connection, in the process of daily use, affected by the environment, mobile phone brand, usage behavior and other factors, it is normal for a short and slight sound to freeze during the process of playing music. Using earbuds at high volume for extended periods of time may damage your hearing. It is recommended to listen, call, and listen to music only at the appropriate volume. Do not rinse or immerse the product in water to avoid malfunction. Do not disassemble products and accessories by yourself to avoid damage and warranty voided.
