Why did the video pioneer become like this?

Is there a basis for "Pioneer really has no position in the field of headphones"? Pioneer headphones/kloc-began to be sold in the domestic market in October, and were sold in Europe and America before. Your former pioneer headphones are either fakes or smuggled goods. You are talking nonsense here. Pioneer is the world's leader in audio, which is known to our parents, but we used to listen to the car audio in the home theater. The above picture is for my own use and the sound quality is very good. It's strange to say that Sony is good, let alone a rambler, and you can simply ignore the headset market.

[The pioneer of the latter is made in China ...] Better. Is Pioneer made in China? You're kidding. Why not just say that Senhai is also made in China?
