Background

The early stage performance monitoring mode uses a loudspeaker as a monitoring system, however, the monitoring of the stage sound playing in this way is prone to damage human ears, which leads to the reduction of hearing function and further causes hearing impairment. Therefore, the earphone device is gradually changed to replace the existing stage monitoring system in the later stage, so that the performer can monitor his own voice or music by the earphone device during performance or performance, thereby avoiding damaging his own hearing.

Accordingly, noise-isolation features (noise-isolation features) of the headphone device are also becoming more and more advanced.
