David Clark DC JET-X: Mismatched for Jet Pilots

When David Clark introduced the Jet-X headset early last year, its intent was clear. This was not a feature-heavy, Bluetooth-laden flagship meant to chase Bose or Lightspeed. Instead, the Jet-X was positioned as a lightweight, durable, on-ear ANR headset designed for pilots operating in relatively quiet jet flight decks. After testing it myself and sending it out to pilots flying a variety of transport-category aircraft, it’s clear David Clark largely delivered on comfort and simplicity, but I think it misjudged where and how the headset would realistically be used. The advice is the same as it ever was—and more important with this David Clark set: Try it before you buy it. Here’s an overview of our exhaustive field report.

Signature Clarks for Everyday Use

David Clark’s legacy is well known. The green ear cups, passive noise reduction, and near-indestructible construction defined generations of pilot headsets, while the company’s excellent support from Worcester, Massachusetts, lives on.

The Jet-X is a departure from David Clark’s traditional design, but it still follows the company’s core philosophy: simple, robust equipment that prioritizes function over flash. The headset weighs just 4.5 ounces, uses a rest-on-ear design, runs its ANR circuitry on a single AA battery, carries FAA TSO approval, and comes with a three-year warranty. There’s no Bluetooth, no audio mixing, and no user-adjustable noise-cancellation modes. What you see is what you get.

Physically, the Jet-X is well executed. The on-ear pads are soft, the headband is comfortable, and the overall clamping force is low enough that it’s easy to forget you’re wearing it during long legs. Despite the extensive use of plastic, the frame is flexible and confidence-inspiring. Nothing about it feels fragile. The boom microphone rotates easily for left- or right-seat use, and the headband adjustment is simple and secure.

One of the most pleasant surprises is how unobtrusive the headset feels once plugged in. The audio cable is thin and light, and the control module is compact enough that it doesn’t tug on the headset or get in the way. Battery life is excellent. I logged roughly 25 hours on a single AA cell without seeing the status light change, which aligns well with David Clark’s 50-hour claim. The automatic shutoff logic is also smartly implemented, reducing the chances of pulling the headset out of your bag with a dead battery.

From a design and ergonomics standpoint, I think this is arguably the most comfortable headset David Clark has produced.

Boeing 737 Flight Trial

I initially tested the Jet-X during a four-day trip flying multiple Boeing 737 variants, including the -800, -900, MAX 8, and MAX 9. As expected, the MAX airplanes are slightly quieter than the NGs, and the -900/MAX 9 are marginally quieter than the -800/MAX 8. None of that ultimately mattered. And to be fair, David Clark said up front that the 737 flight deck might be a challenge for these headsets. But—this is a popular transport platform.

Ground operations were uneventful, with clear audio and stable ANR performance. The moment the takeoff roll began, however, the limitations of the headset became obvious. As noise levels ramped up, the ANR simply couldn’t keep pace. The experience was reminiscent of older passive headsets: increase the volume during takeoff and climb, then back it off once the airplane cleaned up and noise levels dropped. There’s nothing unsafe about this environment, but it’s not where many pilots want to be anymore. Long-term hearing protection has become a serious consideration, and takeoff and landing are where the highest exposure occurs.

To give the Jet-X a fair chance, I went back to a technique many of us used years ago—foam earplugs under the headset. That combination worked surprisingly well. The cockpit was quieter, the headset remained comfortable, and cruise was pleasant. But at that point, the Jet-X was functioning more as an audio delivery device than a primary noise-reduction solution.

After four days and roughly 22 hours of flight time wearing the set, my thoughts remained unchanged. At its selling price ($685), this wasn’t a headset I would personally buy for narrow-body flying.

Expanding the Eval: More Aircraft, More Crews

Since David Clark had already suggested that the 737 might be a challenging environment for the Jet-X, I wanted to see whether the headset fared better elsewhere. I asked several friends to take it on trips in different aircraft. The demo headset ultimately logged time on the Boeing 757, 767, 777, and 787, as well as the Bombardier Global Express. Unfortunately, I wasn’t able to get it into an Airbus flight deck.

What became immediately clear was that aircraft type alone doesn’t determine whether a headset works well. Culture matters just as much. Since this review is aimed at pro pilots flying the transport line, you understand what I mean about culture.

One pilot flying the 757 and 767 reported that his airline’s aircraft aren’t equipped with intercoms, and the standard practice is to use a headset that leaves the inside ear uncovered. He found the Jet-X comfortable, lightweight, and easy to pack, and he specifically noted improved clarity when dealing with strong accents in foreign airspace. But when asked whether he would consider purchasing one, the answer was no. Tucking the inside earcup behind his ear made the headset uncomfortable, and his existing Bose ProFlight fit his needs better.

Two other pilots flew the Jet-X in the 777 and 787. Their feedback echoed many of the same points: excellent comfort, light weight, compact size, and noticeably improved clarity of foreign ATC. One pilot noted that the headset tended to slide slightly when looking down but otherwise had few complaints. Interestingly, one of those pilots said he might consider the Jet-X if shopping for a new headset, while the other ruled it out entirely, citing the lack of intercom use on his fleet and the awkwardness of managing both earcups.

The Bombardier Global Express trial was perhaps the most telling for corporate aircraft. That pilot’s experience closely mirrored mine in the 737. The headset was comfortable and worked well in cruise, but during takeoff, climb, approach, and landing, the ANR simply couldn’t manage the noise environment. Even in an aircraft generally considered quieter than most narrow-body airliners, the Jet-X struggled when it mattered most.

Where the Concept Breaks Down

Looking across all of the feedback, a consistent pattern emerges. The Jet-X performs best in cruise and excels in comfort and simplicity. We found that it struggles during high-noise phases of flight in aircraft where pilots wear headsets continuously from engine start to shutdown. At the same time, the aircraft that are quiet enough for the Jet-X to feel acceptable often operate with cockpit cultures that don’t favor wearing a full on-ear headset for the entire flight.

That leaves the Jet-X in an uncomfortable middle ground. It doesn’t provide enough noise attenuation for airplanes where hearing protection is critical, and it doesn’t align well with the operational habits of crews flying quieter long-haul aircraft.

Final Thoughts

David Clark clearly put significant thought into the Jet-X. The headset is well built, extremely comfortable, easy to live with, and refreshingly simple. But simplicity alone isn’t enough at this price point. Pilots today expect meaningful noise reduction during the loudest phases of flight, not just acceptable performance in cruise.

In the end, the Jet-X feels like a headset designed around a theoretical use case rather than the realities of line flying. For some pilots in specific operations, it may still make sense, and it’s priced right and has exceptional customer support. For most airline pilots, however, I think it misses the mark.
