Audio monitors usage in song making
Audio monitors are the speakers and headphones, we listen the sound on.
Using audio monitors is a specialized activity in a recording studio that focus on testing how the song would sound on different types of monitors.
Recording engineers use audio monitors to monitor and control the volume and left-right panning of the sound. They are one of the important parts of creating good mixed songs.
Some people use headphones instead of big speakers when they are on budget. However, keeping a variety of speakers in your recording room is always a good idea as you can then test different sounds.
