The David Clark DC ONE-XH is a standout in the world of aviation headsets, particularly for helicopter pilots. Its defining feature is the hybrid ENC (Electronic Noise Cancellation) combined with Bluetooth connectivity, offering pilots a quieter cockpit experience while staying connected to their devices. This combination is crucial for reducing fatigue on long flights and ensuring clear communication.
Equipped with a U-174/U plug, the DC ONE-XH is compatible with most helicopter intercom systems, making it a versatile choice for pilots. The M-5B electret microphone, known for its noise-cancelling properties, ensures that your voice is heard clearly, even in the noisiest environments. This headset is designed to meet the demands of professional pilots who require reliability and performance.
In this guide, we'll cover everything you need to know about the DC ONE-XH, from its specifications and noise attenuation capabilities to maintenance tips and part replacements. Whether you're looking to upgrade your headset or ensure it's in top working condition, this guide provides the insights and resources you need.

The DC ONE-XH utilizes a hybrid Electronic Noise Cancellation (ENC) system, which combines passive noise reduction with active noise cancellation technology. This system is designed to significantly reduce ambient noise, allowing pilots to focus on their flight tasks without the distraction of engine and rotor noise. The ENC system is powered by a rechargeable battery, ensuring consistent performance throughout your flight.
Over time, the effectiveness of noise attenuation can diminish due to wear on the ear seals and microphone protector. The ear seals (item 2, part number 15976P-07) should be replaced when they show signs of wear or hardening. Similarly, the microphone protector (item 4, part number 40062G-02) should be checked regularly to maintain optimal noise-cancelling performance.
The DC ONE-XH and DC ONE-XP are both part of David Clark's advanced aviation headset lineup, but they cater to different needs. The DC ONE-XH is specifically designed for helicopter use, featuring a U-174/U plug that is compatible with most helicopter intercom systems. In contrast, the DC ONE-XP is tailored for fixed-wing aircraft, offering a dual GA plug configuration.
Both models share the hybrid ENC and Bluetooth capabilities, providing excellent noise reduction and connectivity. However, the DC ONE-XH's design is optimized for the unique acoustic environment of helicopters, ensuring pilots receive the best possible audio experience.
👉 For helicopter pilots, the DC ONE-XH is the preferred choice due to its plug compatibility and optimized design for rotorcraft environments.

Looking to make your David Clark DC ONE-XH even more comfortable? These two upgrades are customer favorites:
The double-foam head pad kit provides enhanced cushioning, reducing pressure on the top of your head during long flights. It's designed to fit perfectly with the DC ONE-XH, ensuring a snug and comfortable fit.
👉 Upgrade to this head pad for a noticeable improvement in comfort.
These gel ear seals provide a superior seal around your ears, enhancing noise reduction and comfort. The undercut design ensures a better fit, reducing pressure and improving wearability during extended use.
👉 Consider these ear seals for a quieter and more comfortable experience.
By following these maintenance tips, you can ensure your DC ONE-XH remains in optimal condition for years of reliable service.
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.

To replace the ear seals, remove the old seals by gently pulling them away from the ear cups. Install the new leatherette ear seals (part number 15976P-07) by aligning them with the ear cups and pressing them into place.
First, check the battery level in the control module. If the battery is low, recharge it. If the problem persists, inspect the microphone protector (part number 40062G-02) for damage, as this can affect ENC performance.
The DC ONE-XH is optimized for helicopters with its U-174/U plug. For fixed-wing aircraft, consider the DC ONE-XP, which features a dual GA plug configuration.
Replace the headpad (part number 15977P-04) when it shows signs of wear or no longer provides adequate cushioning. Regular inspection will help maintain comfort.
Use a damp cloth to wipe down the headset, avoiding harsh chemicals. For deeper cleaning, consider using Celeste Sani-Com towelettes for safe and effective sanitation.
Ensure the Bluetooth function is activated on both the headset and your device. If connection issues persist, reset the Bluetooth settings on your device and try pairing again.
