Lightspeed Aviation has introduced Delta Zulu, a new ANR aviation headset that includes a built-in carbon monoxide sensor, as well as a built-in audio equalization system that adjusts audio output to compensate for hearing loss.
The built-in carbon monoxide measures carbon monoxide levels in the cockpit any time the headset is turned on. The headset also will produce audible alerts, according to Lightspeed officials.
The companion Lightspeed app allows pilots to personalize their own alert thresholds based on their tolerance and within limitations. With it, they can check CO sensor data visually during flight and review the full sensor history later, officials explained.
Delta Zulu also features HearingEQity, a built-in audio equalization system that adjusts the headset’s audio output to compensate for any individual hearing loss.
Through an automated 12-frequency hearing test that can be taken through the Lightspeed app, HearingEQity sets the hearing level in each ear of the headset to create an individual hearing profile that helps compensate for any hearing variations between ears, company officials explained.

Other features include:
- Cockpit voice recorder: The Lightspeed app also allows pilots to record radio conversations, play back transmissions, and archive flight recordings for post-flight briefing and training.
- Changeable battery packs: Gives customers the option of using rechargeable lithium-ion batteries or AA batteries.
- UAC plug: Allows people to connect to other devices directly from the headset for charging, audio, and data transmissions. It can also be charged while flying via USB. Delta Zulu has options for 4 cable configurations, from UAC to USB-A (included), USB-C, 3.5 mm, and Lightning plugs (optional)
- Personal Safety Data Partnership Program: By opting into the anonymous collection of sensor data from their headset, customers provide data that will be used by general aviation experts and scientists to improve GA’s understanding of safe piloting practices, company officials noted.
Preorders for the new headset can now be placed for shipments in the second half of September 2022. Price: $1,099.

I just looked over the LS website, and I can’t find anything about the life of the CO sensor. Is it a replaceable module? If so, how often?
I like the feature set, especially the audio frequency equalization. So far, though, no headsets I’ve tried equal Bose for wearing comfort If it comes up short there, I would not buy them even with the extra features.
