B& amp； O is an international brand in Denmark. I auditioned in Hangzhou Building. The price of entry-level products is slightly higher. Although I pay more attention to the design and materials of speaker units, I personally think BOSE can be considered at this price. After all, cost performance, international market share and brand heritage are better. Shopping in JD.COM is still guaranteed. More than 95% of the goods inside are genuine, so the installation is relatively simple.
