A-610

Listen-only headphones with dual magnetic receivers

Durability

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.

Adaptability

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.

FAA TSO Approval

The A-610 headphones are certified for aviation use under FAA TSO C57.
