We promise to provide a “3.15 service” for the series of products sold, which includes "three months replacement, one year warranty, and five years paid maintenance."

**Three Months Replacement**  
Users may replace the product with a new unit of the same model within three months from the date of purchase (based on the date of the official purchase invoice) if the speaker malfunctions during normal use, provided there is no visible damage and all accessories are complete.

**One Year Warranty**  
Users are entitled to free warranty service for faults occurring within one year from the date of purchase due to non-human factors during use.

**Five Years Paid Maintenance**  
Users may receive maintenance services within five years from the date of purchase, charging only for the cost of repair materials.

**Special Note**  
The following situations do not qualify for our free warranty service, and you may choose paid services (labor cost + material cost):  
1. Damage caused by human actions (e.g., dents, scratches).  
2. Damage caused by violating product usage instructions.
