Lightspeed Zulu 3 ANR Aviation Headset — Helicopter (U-174)
Strap in and tune out the noise. The Zulu 3 is the headset serious rotary pilots reach for — built almost entirely from stainless steel and magnesium, wrapped in Kevlar-cored cables, and engineered to deliver exceptional Active Noise Reduction flight after flight. This helicopter variant features a single U-174 plug designed for rotorcraft cockpits. Backed by an industry-leading 7-year warranty.
Key Features
Advanced ANR: Superior, consistent quiet across a broad range of low-frequency engine noise. Magnesium ear cups naturally block high-frequency sound.
Rugged Construction: Stainless steel and magnesium build with Kevlar-cored braided cables — resistant to kinking and wear.
Contoured Comfort Fit: Tapered memory-foam ear seals with 20% more surface area than major competitors and 50% more internal ear cup space.
Dual Aperture Disc™ Mic: Noise-cancelling electret microphone with user-adjustable gain screw for crisp voice clarity.
ComPriority™: Automatically lowers Bluetooth or wired audio during active radio transmissions, then eases it back in gently.
Connected in the Cockpit
The Zulu 3 keeps you connected without distraction. Full Bluetooth integration lets you take calls, stream music, or receive audio alerts from your EFB app — all without breaking your scan.
FlightLink compatibility lets you record incoming and outgoing ATC communications directly to your iPad or iPhone via Lightspeed’s free iOS app. Auto Shutoff™ powers the headset down automatically when not in use, so your batteries are always ready when you are.
Built to Last. Backed by Lightspeed.
Every Zulu 3 is engineered for the long haul. The stainless steel and magnesium frame shrugs off the rigours of daily flying, while the Kevlar-reinforced braided cables resist the kinks and fraying that plague lesser headsets.
The U-174 single plug is the standard connection for helicopter cockpits, powered by two AA batteries providing up to 40 hours of ANR use. Backed by Lightspeed’s renowned customer service and 7-year warranty.
