Its robust construction and reliable performance make it a trusted choice for aviators who demand clarity and comfort in the cockpit.
This guide provides a comprehensive look at the H10-26, detailing its specifications, noise attenuation capabilities, and why pilots prefer it over other models. Whether you're looking to maintain, upgrade, or simply understand your headset better, this guide is your go-to resource.
We'll also explore the parts catalog, offering insights into the components that make up the H10-26, and provide tips on how to keep your headset in peak condition. From comfort upgrades to essential accessories, discover everything you need to enhance your flying experience.
The H10-26 is a helicopter-specific headset with a coiled cord and U-174/U plug.
It features the M-7A electret microphone for clear communication in noisy environments.
The headset's passive noise reduction is achieved through its circumaural design.
Compatible with a wide range of helicopters due to its U-174/U plug.
The H10-26 shares many parts with other H10 series headsets, simplifying maintenance.
Comfort upgrades like gel ear seals and double-foam head pads are available for enhanced wearability.

The H10-26 achieves its 24 dB Noise Reduction Rating through passive means, relying on its circumaural ear cup design. This design creates a sealed acoustic chamber around the ear, effectively minimizing ambient noise. The foam ear seals and robust dome construction maintain the integrity of the seal, ensuring consistent noise reduction throughout your flight.
Over time, the effectiveness of noise attenuation can degrade due to wear on the ear seals. Compressed or cracked seals can break the acoustic seal, reducing noise blocking capabilities. If you notice increased noise levels, consider replacing the ear seals. The Undercut Gel Earseal (pair, part number 40863G-02) is a recommended upgrade for maintaining optimal noise reduction.
The David Clark H10-26 and H10-13H are both helicopter headsets, but they serve slightly different purposes. The H10-26 is designed with a coiled cord and U-174/U plug, making it ideal for helicopter use where flexibility and compatibility are crucial. In contrast, the H10-13H offers a similar passive noise reduction but is equipped with a straight cord and a different plug configuration, catering to pilots who prefer a more traditional setup.
Both models share many components, such as the M-7A electret microphone and similar ear cup designs, which means parts like ear seals and head pads are interchangeable. This compatibility simplifies maintenance and part replacement, allowing pilots to keep their headsets in top condition with ease.
For helicopter pilots seeking flexibility and compatibility, the H10-26 is the preferred choice. However, if you need a headset for multiple aircraft types, the H10-13H offers broader utility.
Looking to make your David Clark H10-26 even more comfortable? These two upgrades are customer favorites:
This head pad kit offers enhanced comfort with its double-foam construction, reducing pressure points during extended flights. It's an ideal upgrade for pilots who spend long hours in the cockpit, providing a softer and more cushioned feel.
👉 Highly recommended for improving overall headset comfort.
These ear seals provide a superior seal and comfort with their gel-filled design, reducing pressure around the ears. They are particularly beneficial for pilots who wear their headsets for long durations, ensuring a snug fit without discomfort.
👉 A must-have for enhancing noise reduction and comfort.
By following these maintenance tips, you can ensure your H10-26 remains in optimal condition, providing reliable performance for every flight.
Small accessories make a big difference in headset longevity and comfort.

To replace the ear seals, remove the old seals by gently pulling them off the ear cups. Install new seals, such as part number 40863G-02, by pressing them firmly onto the ear cups until they snap into place.
First, check the connection of the microphone to ensure it's secure. If the issue persists, inspect the M-7A microphone (part number 09168P-33) for damage and consider replacing it if necessary.
The H10-26 is designed for helicopters with a U-174/U plug. To use it in fixed-wing aircraft, you'll need an adapter such as the GA to Helicopter Adapter (part number 18253G-06).
Use a soft, damp cloth to wipe down the headset. Avoid using harsh chemicals. For the microphone, use a windscreen cover to protect it from moisture and debris.
Check the condition of the ear seals. Worn or damaged seals can compromise the noise reduction. Replace them with part number 40863G-02 for optimal performance.
Consider upgrading to the Double-Foam Head Pad Kit (part number 40688G-36) and Comfort-Gel Undercut Ear Seals (part number 40863G-02) for enhanced comfort during extended use.
