Headphones (Monitoring)
Definition
Closed-back or open-back headphones used for audio monitoring, recording, and mixing. Closed-back headphones isolate external sound and are preferred for tracking; open-back headphones provide a more accurate, spacious soundstage and are preferred for critical listening and mixing.
In Simple Terms
Closed-back for recording (they keep sound from leaking into the mic), open-back for mixing (they give a more natural, spacious sound). Mixing only on headphones can mislead your ears — always check on speakers too.
In Practice
A vocalist uses closed-back headphones during recording to prevent the click track and backing track from bleeding into the microphone. The mix engineer monitors on open-back headphones for a more accurate representation of the stereo field.
Common Confusion
Mixing exclusively on headphones can lead to an overly wide stereo image and inaccurate low-frequency decisions. Referencing on speakers remains important even when headphone mixing is primary.
