Noise Attenuation (Active)


The H20-10X utilizes active noise reduction technology to achieve superior noise attenuation, making it ideal for high-noise environments such as piston and turboprop aircraft. This technology actively cancels out ambient noise by generating sound waves that are phase-inverted to the incoming noise, effectively reducing the overall noise level in the cockpit. This feature not only enhances communication clarity but also reduces pilot fatigue during long flights.


To maintain optimal noise attenuation, it is crucial to ensure that the Flo-Fit Gel Earseals (item 9, part number 40243G-10) are in good condition. Over time, these seals can become compressed or damaged, compromising their ability to form a proper seal around the ears. Regular inspection and replacement of the ear seals will ensure that the headset continues to provide effective noise reduction.

What's the difference between the David Clark H20-10X and H20-10?

The primary difference between the David Clark H20-10X and the H20-10 lies in their noise reduction capabilities. The H20-10X features active noise reduction, which actively cancels out ambient noise, making it more suitable for high-noise environments. In contrast, the H20-10 relies on passive noise reduction, which is effective but not as comprehensive as active noise cancellation.


Both models share similar design elements, such as the over-ear configuration and the use of Flo-Fit Gel Earseals for comfort. However, the H20-10X's active noise reduction system requires a power source, adding a slight weight increase compared to the passive H20-10 model.


Parts Compatibility

  • Flo-Fit Gel Earseals (part number 40243G-10) are compatible with both models.
  • The M-7A Electret Microphone (part number 09168P-33) is used in both headsets.
  • Headband Assy Kit (part number 18900G-87) is interchangeable between the two models.

For pilots who frequently fly in high-noise environments, the H20-10X's active noise reduction offers a significant advantage. However, for those who prefer a simpler, passive system, the H20-10 remains a reliable choice.
