After buying it back and experiencing it for a period of time, the sense of such a large frame weight is lacking. The fineness of the shell material really needs to be strengthened. The most serious thing is that the earphone imitates the soft turning of the ribbon, and the gap between the pieces is not very uniform. It is difficult to express the soft texture with hard materials. Many problems such as cost reduction and assembly need to be considered when landing. Every ordinary product is the result of polishing, which is not easy!
Quality is often controlled by structural engineers in the research and development design stage. Without the whole system to design the structure, the product cannot be made well.
Designers are designs, but the quality of landing products is ugly. I'm sorry for such a good design
