Therefore, a metal tube, such as a gooseneck, is sleeved on the earphone line 7, and the design mode can ensure that the earphone line can be formed into any shape. Wherein, the metal tube can be made of stainless steel, steel and copper wires.
It should be noted that the first headphone shell 1 may be a left headphone shell, and the second headphone shell 5 is a right headphone shell, or the first headphone shell 1 is a right headphone shell and the second headphone shell 5 is a left headphone shell, and in practical application, it is determined whether the first headphone shell 1 or the second headphone shell 5 is a left headphone shell as needed.
