Precautions

Do not soak the earphones in seawater or saltwater for extended periods. Rinse the magnetic charging part with fresh water after use.
If not used for a long time, charge the battery at least once a month.
Do not disassemble any part of the product without authorization. If a defect is found, stop using the product immediately and contact the seller for after-sales service.
After each exercise, wipe off any water on the headset surface, especially around the magnetic charging port, to prevent sweat and saltwater from corroding the port and affecting product lifespan.
Keep the product away from fire, heat sources, freezing sources, and chemicals. Avoid violent impact, disassembly, and extrusion.
Use a charging head with an output of 5V/1A or less. Charging with more than 5V may cause the earphone to overheat, potentially damaging the battery and motherboard.
