The neck of the headset plug is the weakest part. Frequent bend will cause a problem of one earphone working and the other does not. However, the design of a spring-like neck can effectively prevent this problem. Such a design can enhance the intensity and elasticity of the material. The appearance will not change much, and people can use their earphones easily and bend the neck of the headset plug at will without worrying about causing any problems in the future.
