The David Clark DC ONE-X headset stands out with its hybrid ENC technology and Bluetooth connectivity, providing pilots with an immersive audio experience while maintaining essential communication clarity. This model is engineered for comfort and performance, featuring plush ear seals and a lightweight design that reduces fatigue during long flights. The DC ONE-X is equipped with dual GA plugs, making it compatible with a wide range of general aviation aircraft without the need for additional adapters.
In practical cockpit terms, the DC ONE-X's hybrid ENC technology actively reduces ambient noise, allowing pilots to focus on critical audio cues and communications. The Bluetooth feature adds convenience, enabling wireless connectivity for personal devices, which is particularly useful for receiving audio alerts or enjoying entertainment during less demanding phases of flight.
This guide covers everything you need to know about maintaining and upgrading your DC ONE-X headset. From detailed parts lists to comfort upgrades and adapter options, we've got you covered. Whether you're looking to replace worn components or enhance your headset's functionality, this guide provides the insights and resources you need to keep your DC ONE-X performing at its best.

The DC ONE-X achieves its impressive noise reduction through a combination of passive and active methods. The passive noise reduction is provided by the circumaural ear cups, which create a sealed acoustic chamber around the ears. This design is complemented by the active ENC system, which uses microphones to detect ambient noise and generate anti-noise signals to cancel it out. This hybrid approach results in a significant reduction in cockpit noise, allowing pilots to focus on communication and navigation without distraction.
Over time, the effectiveness of the noise attenuation can be affected by the condition of the ear seals. Worn or damaged seals can compromise the acoustic seal, reducing the headset's ability to block external noise. If you notice a decrease in noise reduction, consider replacing the ear seals. The Leatherette Ear Seals with Memory Foam (part number 15976P-07) are a recommended replacement to maintain optimal performance.
The primary difference between the DC ONE-X and the DC ONE-XP lies in their power sources and connectivity options. The DC ONE-X is powered by a battery module, while the DC ONE-XP is panel-powered, eliminating the need for batteries and offering a more streamlined setup. Both models feature Bluetooth connectivity, but the DC ONE-XP offers additional integration options for aircraft panels, making it a preferred choice for pilots who prioritize cockpit integration.
In terms of parts compatibility, many components are shared between the two models, including the headpad and ear seals. This means that pilots can easily find replacement parts for either model without worrying about compatibility issues. However, specific parts related to power supply and connectivity may differ, so it's essential to verify part numbers when ordering replacements.
For pilots deciding between these two models, consider your cockpit setup and whether you prefer battery power or panel integration. Both headsets offer excellent noise reduction and comfort, but the DC ONE-XP's panel power can be a significant advantage for those with compatible aircraft systems.
Looking to make your David Clark DC ONE-X even more comfortable? These two upgrades are customer favorites:
This head pad kit provides enhanced comfort with its double-foam construction, reducing pressure on the head during long flights. It's a direct replacement, ensuring a perfect fit without any modifications.
👉 Ideal for pilots who spend extended hours in the cockpit and need maximum comfort.
These ear seals provide a superior acoustic seal, enhancing noise reduction and comfort. The gel material conforms to the shape of your head, ensuring a snug fit that minimizes pressure points.
👉 Perfect for pilots seeking improved noise isolation and comfort during long flights.
Maintaining your DC ONE-X with these tips will ensure it remains reliable and comfortable for every flight.
The H10-13Y uses standard dual GA plugs — a PJ-068 for audio and a PJ-055 for the microphone — which are compatible with virtually all general aviation aircraft intercoms. However, as young pilots progress and fly different aircraft types, adapters become essential for connecting a GA-terminated headset to alternative intercom systems or Bluetooth devices.
👉 A GA-terminated headset like the H10-13Y pairs with the right adapter to stay compatible across every aircraft a student pilot is likely to encounter.
Small accessories make a big difference in headset longevity and comfort.
At Pilots HQ, we believe our job isn't finished when you buy a headset. We go further by offering:
👉 With Pilots HQ, you're not just buying products — you're investing in long-term comfort, clear communication, and confidence every time you fly.
Check the headpad (part number 15977P-04) and ear seals (part number 15976P-07) for wear. Replacing these parts can restore comfort.
Ensure the ear seals are in good condition and properly seated. Worn seals can reduce noise attenuation effectiveness.
The DC ONE-X is compatible with most general aviation aircraft due to its dual GA plugs. Check your aircraft's audio panel for compatibility.
Ensure your device's Bluetooth is updated and within range. If issues persist, try resetting the headset's Bluetooth settings.
The microphone (part number 09168P-85) can be replaced by following the instructions in the user manual or contacting Pilots HQ for guidance.
One common issue is reduced noise cancellation due to worn ear seals. Regularly inspect and replace them to maintain performance.
