David Clark PRO-2 Headset - passive, XLR-5 Plug (5

Next generation David Clark PRO-2 passive noise-attenuating headsets combine outstanding comfort, performance and durability in a lightweight, rest-on-ear design. These headsets are ideal for commercial pilots that fly low-noise aircraft where Electronic Noise Cancelling ANR technology is not required. The David Clark PRO-2 headsets provide enhanced audio quality and clear, crisp voice transmission utilizing advanced, noise-cancelling electret microphones.

·       Enhanced audio performance and M-5B electret noise-cancelling microphone for clear voice transmission

·       Soft, Outlast® technology, heat absorbing head pad keeps you cool and comfortable in flight

·       Superior passive noise attenuation for a rest-on-ear style headset

·       Plush, rest-on-ear (supra aural), leatherette ear seals reduce heat buildup

·       Rugged, yet lightweight alloy suspension, less than 8 ounces

·       Swivel hinge stirrup dramatically dissipates clamping pressure

·       FAA TSO-C139a approved
