Listen-only headphone with dual magnetic receivers. The receiver and microphone housings are constructed of high-impact plastic. The headband consists of two spring-steel wires sheathed in vinyl. The headband wires terminate in plastic dress caps to prevent disengagement of the receiver's housings. The headband wires extend down through slots in each receiver housing and provide a minimum of 2-1/2" of vertical adjustment. The receiver housings are capable of limited rotation to fit the head contour. The A-610 headphones are certified for aviation use under FAA TSO C57.
