Noise Attenuation


The DC ONE-XA employs hybrid ENC technology to achieve its impressive noise attenuation capabilities. This system combines passive noise reduction with electronic noise cancellation, effectively reducing ambient cockpit noise. The headset's over-ear design and high-quality ear seals create a physical barrier against external sounds, while the ENC system actively counteracts low-frequency noise.


Over time, the effectiveness of noise attenuation can diminish due to wear and tear on the ear seals. Compressed or damaged seals can break the acoustic seal, leading to increased noise levels. Regular replacement of ear seals, such as the Leatherette Ear Seals (part number 15976P-07), is recommended to maintain optimal performance.

What's the difference between the David Clark DC ONE-XA and DC ONE-XP?

The DC ONE-XA and DC ONE-XP are both part of David Clark's advanced aviation headset lineup, but they cater to slightly different needs. The DC ONE-XA is designed with Bluetooth connectivity, making it ideal for pilots who value wireless audio streaming and connectivity with mobile devices. In contrast, the DC ONE-XP focuses on panel-powered operation, eliminating the need for batteries and ensuring continuous power during flights.


Parts Compatibility

  • Both models share the M-5B electret microphone, ensuring consistent communication quality.
  • The headpad and ear seals are interchangeable between the two models, simplifying maintenance.
  • Bluetooth components are unique to the DC ONE-XA, while the DC ONE-XP features specific panel power components.

For pilots who prioritize wireless connectivity, the DC ONE-XA is the better choice. However, if panel power is a key requirement, the DC ONE-XP offers a more suitable solution.
