Self-monitoring for headphones is the ability to hear yourself through your headphones while you’re recording or performing. This can be helpful for staying in time and pitch, and for hearing how your voice or instrument sounds in the mix.
Many audio interfaces and mixers have a built-in self-monitoring feature. To enable self-monitoring, you’ll typically need to connect your headphones to the headphone output of your audio interface or mixer, and then turn on the self-monitoring switch or knob.
