Specs at a Glance

  • Model Number: H10-56N
  • Part Number: 19529P-71
  • Microphone: M-101/AIC noise-cancelling
  • Design: Over-ear

Noise Attenuation (Passive)

The H10-56N achieves its noise reduction through passive means, relying on the design of its ear domes and seals. The circumaural ear cups create a sealed environment around the ears, effectively blocking out external noise. This design is particularly effective in reducing ambient cockpit noise, allowing pilots to focus on communication and navigation.


Over time, the effectiveness of noise attenuation can degrade due to wear on the ear seals. If you notice an increase in ambient noise, it may be time to replace the ear seals. The Undercut Gel Earseal (pair, part number 40863G-02) is a recommended replacement to restore optimal noise reduction.

What's the difference between the David Clark H10-56N and H10-66?

The David Clark H10-56N and H10-66 are both high-quality aviation headsets, but they cater to slightly different needs. The H10-56N is designed for general aviation use with its passive noise reduction and robust build. In contrast, the H10-66 offers dual impedance capabilities, making it suitable for both civilian and military applications.

Parts compatibility between the two models is generally good, with many components like the headband spring and ear seals being interchangeable. However, the H10-66's dual impedance feature requires specific components not found in the H10-56N.


Key Differences

  • Impedance: H10-56N is single impedance, while H10-66 is dual impedance.
  • Application: H10-56N is ideal for general aviation, whereas H10-66 suits both civilian and military use.
  • Parts Compatibility: Many parts are interchangeable, but check specific components for impedance-related differences.

For pilots primarily in civilian aviation, the H10-56N offers a straightforward, reliable choice. Those needing flexibility for military applications might consider the H10-66 for its dual impedance feature.
