Engineered for the rigorous demands of U.S. Armed Forces, NATO, and major mission command centers, this headset delivers an unparalleled listening and speaking experience in the loudest environments.

Superior Electronic and Passive Noise Reduction

The H10-66XL excels in its ability to offer advanced passive and electronic noise attenuation. This dual layer of protection not only significantly reduces aircraft cabin noise or ground environment sounds but also dramatically improves communication intelligibility. You will experience a remarkable reduction in ambient noise, which is crucial for concentration and operational safety in critical missions and long-duration flights.

Clear, Reliable Communications with M-87 Dynamic Microphone

At the heart of clear voice transmission is its MIL-PRF-28542 (USAF Specifications) certified M-87/AIC dynamic noise-canceling microphone. This microphone is designed to provide crisp and reliable communication, even in extremely noisy environments. Furthermore, its switchable low impedance (5 or 150 ohms) allows for exceptional versatility, adapting to various communication system configurations.

Its flexible, 260° rotatable low impedance wire boom microphone allows for precise positioning, ensuring your voice is captured with maximum fidelity regardless of your position.
