Hands-on: Flying with Lightspeed’s Delta Zulu Headset
Lightspeed aims to usher in a new era of sensor-equipped headsets to make flying safer.

Lightspeed unveiled its newest pilot headset, the Delta Zulu, in September 2022, and since then I was able to test it in a typical piston airplane and in a single-engine turboprop. The Delta Zulu is similar in size and configuration to Lightspeed’s Zulu 3 but adds more active-noise canceling (ANR) technology and a unique audio equalization system as well as a carbon monoxide sensor.

For comparison purposes during these flights, I tried the Delta Zulu and a Bose A20 ANR headset. It is admittedly a somewhat subjective test, but I found the Delta Zulu to be quite comfortable and with excellent noise-canceling. Either headset does a great job of canceling noise, but the added features of the Delta Zulu might make it a more attractive purchase for some pilots.
