Even if the key event is the same, when the key is in different mode states of the earphone, different functions can be defined, for example, when the music state is played, the play pause function corresponding to the key clicking event is designated; when the playing of the music is paused, the key clicking event corresponds to the music playing function; when an incoming call arrives, the key clicking event corresponds to a call answering function; in the communication process, the key clicking event corresponds to a telephone hanging function. In stereo, the left and right volume levels and the scene are generally synchronized consistently, and independent adjustments are not required. Some advanced/assisted headphones may define the left and right channel volume and be assisted with hearing aid parameter compensation.

For example: for the stereo earphone, the keys of the function bin at one side are multifunctional keys, so that the functions of code matching, on-off, sound effect scene/hearing aid scene setting, telephone answering, system parameter resetting, music head up/down, music playing/suspending and the like can be realized; and may further define other features such as broadcast modes; the two keys of the function bin at the other side realize the functions of volume increment, music up/down, music play/pause, sound effect scene/hearing aid scene setting and the like. For the independent earphone of the left and right sound channels, the key of the function bin on one side is a multifunctional key, so that functions of on-off, reset and the like are realized, other characteristic functions such as a broadcasting mode can be further defined, and the two keys of the function bin on the other side respectively realize functions of acoustic parameter setting, music parameter setting, telephone function definition, bluetooth function definition and the like of the left and right sound channels; the keys on the two sides simultaneously define the corresponding channel volume adjusting function and the key multiplexing definition; the distinction and definition can also be made by key events such as single click, double click, triple click, long press, ultra long press, etc. If three keys are arranged in the function bin, the combination of two keys and one multifunctional key for realizing acoustic parameter adjustment can be adopted.
