The Delta Zulu from Lightspeed Aviation introduces a new class of aviation headset, combining the latest noise reduction technology with lifesaving carbon monoxide alerts. Add in customisable audio profiles and complete Bluetooth support, and Delta Zulu just might be the smartest headset you’ve ever worn.

Delta Zulu is built for your mission with safety, control, and comfort in mind. Our newest headset includes Lightspeed’s best ANR to date, with the superior comfort and durability you expect from a Zulu, while also introducing groundbreaking new technologies that could save the lives of both pilots and passengers.

Lightspeed’s designers and engineers collaborated with a team of highly qualified flight and safety experts to develop a revolutionary digital platform and groundbreaking new technologies to make flying safer. Kanari™ smart alert technology built right into the headset provides protection by measuring cabin carbon monoxide levels, helping to keep you and your passengers alert and safe with audible warnings. Our free Lightspeed App allows you to also check the CO sensor data visually during flight, and review your full history later.

The Delta Zulu also introduces a built-in audio equalization system called HearingEQity™ that ensures crystal clear flight communication. Through an automated 12-frequency hearing test that can be taken through the Lightspeed app, HearingEQity sets the hearing level in each ear of your headset to create your individual hearing profile to compensate for any hearing variations between ears.

The Lightspeed App also allows you to record radio conversations, playback transmissions, draw diagrams, and archive flight recordings for post-flight briefing and training. Delta Zulu is also the first headset to adopt the UAC plug, allowing you to connect to other devices directly from the headset for charging, data communications, and auxiliary audio.

The legendary Zulu comfort and durability continues in the Delta Zulu. Performance ear seals, sturdy cables built around a Kevlar core, full Bluetooth integration, and an industry-best 7-year warranty, are still standard in our newest model.



Built-in carbon monoxide detector

The Lightspeed Delta Zulu is the first headset with a built-in carbon monoxide detector and alerting system. It works right out of the box: simply put the headset on and press the power button—you’ll automatically get audio alerts anytime unsafe levels of CO are detected. Because you use a headset on every flight, you’ll enjoy always-on protection and never have to worry about carrying a separate CO detector. Use the free Lightspeed app (for iOS devices) to get historical CO trends or adjust alert levels to suit your preferences.

Flexible power options

Keeping your Delta Zulu powered is easy with the standard rechargeable battery pack. This slim battery lasts for 30 hours and can be recharged in flight from a battery pack or cigarette lighter plug (sold separately). If you forget to charge the battery, quick-change to the AA battery pack in seconds to enjoy 15-20 hours of backup power. Or choose the panel-powered (Lemo plug) model for battery-free convenience.

Custom audio profiles

Lightspeed has always offered some of the finest audio quality of any aviation headset, especially when listening to music, but it’s even better on Delta Zulu. Use the Lightspeed app to complete a one-time hearing test and the headset’s new Hearing EQity feature will customize the audio experience in each ear to maximize clarity. Ideal for pilots with moderate hearing loss, it’s like having your own sound engineer on board for every flight.

Rugged construction

Delta Zulu is built to last, with a rugged stainless steel headband, tangle-free cables wrapped in Kevlar, and an unmatched seven year warranty. Thoughtful design choices abound, including a control box where both cables come out the top and a crush-proof carrying case.


Lightspeed’s best ANR yet

While Delta Zulu might look like an upgraded Zulu 3, under the hood everything is new. It uses additional microphones and dual processors to create Lightspeed’s quietest headset yet. You’ll be able to understand air traffic control more easily and arrive at your destination less fatigued.

Full Bluetooth features

As you would expect with a premium ANR headset, Delta Zulu has complete Bluetooth integration. Listen to music in flight (a passenger favorite) or make phone calls on the ground and enjoy the headset’s noise cancellation to make everything clearer.



  • Built-in carbon monoxide sensor– Always on and always monitoring cabin carbon monoxide, the new CO sensor is optimally calibrated to provide audible and visual warnings at preset or user defined CO thresholds.
  • HearingEQity™ for custom sound– Based on results from a custom 12-frequency hearing test in the new Lightspeed app, HearingEQity automatically adjusts Delta Zulu to optimise every ATC call and conversation specifically for your individual hearing profile. Individualised profiles can be saved, and different headset users can switch profiles.
  • Changeable battery packs– Easy-to-replace battery pack gives you the option of using rechargeable lithium-ion batteries or AA batteries.
  • * The Lightspeed App– Allows you to check sensor data visually during flight, supplying you with instantaneous readouts and historical data. Review safety metrics from prior flights, record conversations, playback transmissions, draw diagrams, and archive flight recordings onto your phone or mobile device for post-flight briefing and training.
  • Bluetooth– Bluetooth wireless technology with A2DP technology enables cell phone communications and stereo music streaming along with alerts from aviation apps.
  • Low-profile comfort– Weighing just 14.9 ounces (including ear seals, head pad and mic boom), Delta Zulu has a low-profile, stainless-steel headband that follows the curve of the head for more comfortable distribution of weight and side pressure.
  • High-performance fit– Delta Zulu’s tapered performance ear seals are designed to hug the curve of the jaw for a natural fit, increasing comfort and clarity while also providing a better seal around eyeglass or sunglass frames. Cup cavities allow the entire ear to fit comfortably inside.
  • Durability and longevity– Made almost entirely of stainless steel and magnesium with durable cables built around a Kevlar core, Delta Zulu is designed to endure the harshest flying environments and last for years to come.
  • Superior quiet– Delta Zulu delivers advanced active noise reduction (ANR) performance over a deep, broad range of low-frequency noise. The magnesium ear cups are superior at blocking out high-frequency noise.
  • Clear comms– The Dual Aperture Disc microphone provides greater noise cancellation for clearer, more intelligible communications. Exclusive, user-adjustable mic gain helps balance loud and soft voices in a multi-headset environment.
  • UAC plug– Delta Zulu is the first headset to adopt the UAC plug, allowing you 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).
  • ComPriority™– Never miss important radio communications with patented ComPriority, which automatically lowers the volume of any auxiliary device during radio or intercom transmissions. The soft mute feature gently eases music back in for a smooth listening transition.
  • Auto Shutoff™– Lightspeed’s proprietary Auto Shutoff feature saves battery life by automatically shutting down the headset power when not in use.
  • Included accessories– Carrying case, single port wall charger, lithium-ion battery cartridge, AA battery cartridge, UAC to USB-A cable, a cord shirt clip, and a set of personalised icon chips to distinguish multiple headsets. 60-day money-back guarantee – We know that every cockpit and pilot is different. That’s why we offer a 60-day money-back guarantee. If you are not completely satisfied with your purchase for any reason, return the product for a full and prompt refund.
  • Available configurations– Dual GA, LEMO panel power, U-174. Others available by special order. Please contact Customer Support if your configuration is not listed.
  • 7-year limited warranty– The BEST in the aviation industry. Lightspeed stands by the quality of the Delta Zulu with a comprehensive 7-year warranty of materials and workmanship.
  • Personal Safety Data Partnership Program – An invitation to join the cause of reducing aviation accidents. By opting into the ANONYMOUS collection of sensor data from their headset, customers are providing data that will be used by General Aviation experts and scientists to improve the community’s understanding of safe piloting practices.


* The Lightspeed App is NOT REQUIRED to use the Delta Zulu ANR headset. For primary Android device users, an iOS device is only needed to set up your HearingEQity™ profile along with carbon monoxide preferences and PPM settings for the first time accessing the Lightspeed App. You may use any iPhone or an iPad or other similar Apple device with iOS version 13 or higher. Your personalized hearing profile and CO alert preferences will be saved in your headset after you complete the set-up process, eliminating the need to have an iOS device for future use with your Delta Zulu.

Please note that while some additional convenient functions on the App will not be available without regular access to an iOS device, the important safety features of Delta Zulu are stored in the headset itself. Once set up, they will automatically deliver improved flying safety.
