Today, I chatted with the Sennheiser counter of Nanjing Suning International Trade Store. He is the Sennheiser counter directly supplied by Shanghai. It is said that several shipments handled by Jin Yi have problems. To put it bluntly, the goods of Jinyi are all processed by ourselves, so the credibility of Jinyi is unknown. If there is a local direct supply counter, you'd better buy it there, at least you can rest assured.
