For more than a decade, Professional Pilot magazine has conducted a headset preference survey that takes the pulse of a community of aviators that places especially rigorous and exacting demands on headsets. Lightspeed Aviation ranked #1 in their most recent survey against other major brands while demonstrating a clear advantage in comfort and overall delivered value. A number of those pilots flew the two leading brands and Lightspeed Zulu was preferred 3 to 1 by pilots who flew with both.
