Verdict. The DC ONE-X is the David Clark ANR headset to shortlist. It does not beat the Lightspeed Zulu 3 on price or warranty length in the listings checked for this page. The passive H10-13.4 remains the David Clark to buy if you do not need ANR.
This page used to orbit an older David Clark ANR model and a photo of a passive H10. The headset to talk about now is the DC ONE-X. The picture above is a placeholder. We do not have a product photograph of the ONE-X, and we are not using the H10-13.4 photo in its place.
What Aircraft Spruce and David Clark list
The dual-GA battery ONE-X was $1,020 at Aircraft Spruce for this update (David Clark part 43102G-01). The feature list on that page includes hybrid feed-forward and feed-back noise cancellation, Bluetooth, a mono/stereo switch, an M-55 electret mic, leatherette ear seals, an Outlast head pad, a folding alloy suspension, two AA batteries rated up to 50 hours, a weight of 12.3 ounces without the cord, TSO-C139a approval, a 5-year warranty, and a 30-day return. Panel-power and helicopter configurations exist as separate part numbers. We did not find a certified NRR to set beside the H10-13.4's 23 dB.
David Clark does not show a public MSRP on the pages we used. The $1,020 figure is a retailer price.
How it sits against the Zulu 3 and the A30
The Zulu 3 is $71 less at list and carries a 7-year warranty. The A30 is $279 more than the ONE-X and adds three ANR modes, with a 5-year warranty like the ONE-X. Without a shared noise measurement, this site will not rank the ONE-X as quieter or louder than either one. The reason to buy it is that you want David Clark's ANR headset specifically: the suspension, the mic, the TSO, the battery claim.
The reason to skip it is the same money spent on a Zulu 3 with two extra warranty years, or on an A30 if you have already decided on Bose.
The passive David Clark is a different product
The KA-1 is the best passive headset in the main table. The H10-13.4 is the certified, most proven passive alternative. Both have no ANR and no Bluetooth, which is the point. The comparison with the KA-1 is the page for that choice. The KA-1 is not an alternative to the ONE-X for a pilot who came here for active cancellation.
Questions pilots ask
Is the DC ONE-X the current David Clark ANR headset?
It is the current hybrid-ANR model this review covers. The older H10-13X is a different electronic-noise-cancelling headset still mentioned in some catalogs. This page does not re-certify that the H10-13X is in production.
DC ONE-X or Lightspeed Zulu 3?
The ONE-X listing used here is $1,020 with a 5-year warranty and up to 50 hours of battery life. The Zulu 3 is $949 with a 7-year warranty and up to 40 hours. Buy the ONE-X if you want to stay with David Clark. Buy the Zulu 3 if warranty length and price lead.
Does the ONE-X replace the H10-13.4?
No. The H10-13.4 is passive, with a certified 23 dB NRR and no Bluetooth. Buy that model if you do not want ANR. The KORE KA-1 is another passive option, with no ANR and no Bluetooth, at $224.95.
Does the DC ONE-X have Bluetooth?
Yes. The dual-GA battery listing used here is $1,020 at Aircraft Spruce. The warranty on that listing is 5 years.
How long does the ONE-X battery last?
The Aircraft Spruce listing says up to 50 hours from two AA batteries. The Zulu 3 user guide says up to 40 hours, and heavy Bluetooth use reduces that. The ONE-X warranty is 5 years.
How much does the DC ONE-X weigh?
12.3 ounces without the cord, on the listing used here. The Zulu 3 lists 14.6 ounces including the ear seals and the mic boom. This site has no ONE-X product photo.
Does the ONE-X have a certified NRR?
No certified NRR was on the retailer listing used here. The passive H10-13.4 publishes a certified 23 dB NRR. The ONE-X is hybrid ANR and lists at $1,020.
