Lightspeed’s designers and engineers collaborated with a team of highly qualified flight and safety experts to develop a revolutionary digital platform and ground breaking 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 equalisation system that ensures crystal clear flight communication. Through an automated 12-frequency hearing test that can be taken through the Lightspeed app, this 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.
