David Clark H10-76 Military Aviation Headset: Low Impedance, Superior Comfort & Noise Reduction for Pilots 12510G-21

What aircraft and communication systems is the David Clark H10-76 designed for?

The H10-76 is engineered for military aircraft operations, including helicopters in high-vibration conditions and ground support around high-noise aircraft. It is a low impedance headset terminating in a single military U-174/U plug, so it connects to military aircraft and helicopter intercom systems rather than standard civilian general aviation panels.

What microphone does the H10-76 use and how clear are transmissions?

The H10-76 uses the M-87 dynamic noise-canceling microphone, built to meet rigorous USAF specifications. It cancels surrounding cockpit noise so your transmissions stay clear and intelligible over jet engines, rotor wash, and other high-noise aircraft environments where reliable communication matters most for aircrew and ground support personnel.

How much noise does the H10-76 block, and does it use active noise reduction?

The H10-76 is a passive headset with no active noise reduction electronics and no batteries. It relies on a Noise Reduction Rating of 24 decibels, achieved through undercut comfort gel ear seals and a sealed design. This passive attenuation meaningfully lowers background cockpit noise without any power source or battery module.

Does the H10-76 have Bluetooth or an auxiliary audio input?

No. The H10-76 does not include Bluetooth wireless connectivity and does not have an auxiliary audio input. It is a communication-focused military headset built around the M-87 dynamic boom microphone and the U-174/U plug, so it does not connect to phones or music devices for entertainment audio.

What plug and cord does the H10-76 use, and will it fit civilian general aviation aircraft?

The H10-76 is a low impedance headset that terminates in a single military U-174/U plug on a 5-foot coiled cord, designed for military aircraft and helicopter systems. It does not fit standard civilian twin-plug general aviation panels out of the box, but it can be adapted using appropriate conversion accessories.

What does an H10-76 civilian conversion accessory do?

A conversion accessory lets you adapt the military H10-76 for use in civilian general aviation aircraft by changing the single U-174/U plug arrangement to suit standard twin general aviation panels. These conversion accessories are sold separately and are not included with this headset, so confirm compatibility for your specific aircraft before purchasing.

How much does the David Clark H10-76 weigh and is it comfortable for long flights?

The H10-76 weighs about 19 ounces. It features undercut comfort gel ear seals that reduce pressure and an expanded head pad designed to help eliminate hot spots, spreading weight evenly across the head. This is built for extended wear during multi-hour missions and long-duration ground support work around high-noise aircraft.

Why is the H10-76 considered a military standard headset?

The H10-76 is engineered for demanding military aircraft operations and is trusted by U.S. Air Force pilots and NATO command centers worldwide. Its USAF-spec M-87 microphone, robust construction, and low impedance design make it dependable equipment for aircrew and ground support personnel working around high-noise aircraft in mission-critical conditions.

What is the manufacturer part number, and does the H10-76 have a National Stock Number?

The David Clark H10-76 carries manufacturer part number 12510G-21. If you are procuring through a government supply channel that requires a National Stock Number, confirm the current NSN against official procurement records before ordering, since stock numbers are maintained separately from the manufacturer part number listed on this product page.

What is the difference between the H10-76 and the H10-76XL?

The H10-76 is a passive noise-attenuating headset with no electronics or battery. The H10-76XL is the active noise cancelling version that adds electronic noise reduction and runs on a battery module. If you want pure passive performance without batteries, the standard H10-76 is the model on this page.

What comes with the H10-76 and what warranty does it carry?

The H10-76 ships new with its undercut comfort gel ear seals and expanded head pad installed, plus a 5-foot coiled cord terminating in a U-174/U plug. It is backed by a David Clark manufacturer warranty. Because warranty length is stated differently across our own product fields, review the warranty terms on this product page for exact coverage.
