Introducing Lightspeed Delta-Zulu

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.

Improved pilot safety

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 optimize every ATC call and conversation specifically for your individual hearing profile. Individualized profiles can be saved, and different headset users can switch profiles.

Greater personalization

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.

Other modern conveniences and sustainability

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)

Changeable battery packs
Easy-to-replace battery pack gives you the option of using rechargeable lithium-ion batteries or AA batteries.

Community participation in safety

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.
