Why use mono audio on Android?

The mono audio function takes care of combine the two channels into one. In this way, both what should sound through the right earphone and what is reproduced through the left earphone are transmitted through the same channel. Although stereo sound enhances the listening experience and helps the user to better enjoy each instrument during a song, it is not always a recommended option. Why?

Some users may have hearing problems in only one ear. Suppose that in a song an instrument is played through the left channel and the voice through the right channel. Depending on the ear in which the limitation is located, the user will only hear the music or the voice. Combining all channels into one, that is, using mono audio, prevents nuance from being lost in songs or other sounds, such as those found in video games.
