Headsets, communication tools designed to be worn on the head, facilitated hands-free interaction, particularly among pilots and crew members aboard expansive starships. These devices typically featured either one or two earpieces, though certain models were known to encompass a substantial portion of the wearer's head.
Dating back to the High Republic Era, it was common practice for almost all Jedi to utilize headsets for communication with fellow pilots or their astromech droids. A prime example is Obi-Wan Kenobi's use of one during his aerial battle with Jango Fett while in orbit around the planet Geonosis.
Imperial personnel, such as ensign Cauley, a tactical officer serving on the Imperial-class Star Destroyer Ultimatum, employed headsets while on duty on the ship's bridge.
