Abstract
Abstract A communications headset has two earpieces mounted on a headband, one at each end. The earpieces are mounted on the headband by arcuate members or stirrups which provide for pivoting of the earpieces about an axis in the plane of the headband, or parallel thereto. A boom attachment member is rotatably mounted on the back of one of the earpieces and the boom is mounted on the attachment member for pivotal and swinging movement. A receiver can be in both earpieces or only in the earpiece carrying the boom. The boom carries an electret microphone and associated amplifier.
