Headset (Earth-5875)

A headset is the combination a headphone with a microphone. Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). Headsets provide the equivalent functionality of a telephone handset but with handsfree operation. They have extensive use in the UNSC Marine Corps as well as civilian life.

The standard issue M10 Pattern Ballistic Helmet and the head mounted sights of the UNSC Marine Corps have integrated headsets for communication.

History
Many headsets were used by both the UNSC Marine Corps and the Office of Naval Intelligence during both the Secession and the First Contact War.
