The Lightspeed Zulu 4 headset is the successor to the legendary Zulu series, which has earned a reputation among pilots as the number one premium ANR headset. The new generation goes even further, bringing more comfort, more clarity, and more flexibility, so you can focus on what matters most: a safe and precise flight.
Zulu 4 takes communication to the next level with AINR (AI-enhanced Noise Reduction) technology, which intelligently suppresses noise. Improved Bluetooth transmission reduces noise by up to 90%, ensuring your voice is heard clearly whether you’re communicating with ATC or making a call on the ground. In lab tests conducted in 95 dB environments and compared with David Clark One-X and Bose A30, Zulu 4 demonstrated excellent performance in engine noise reduction. The dual-shield Disc™ microphone further eliminates engine and wind noise, while the adjustable mic gain ensures optimal volume in every situation. Enjoy music with Front Row Center™ (FRC) stereo crossfeed, delivering faithful, clear, and rich sound directly in the cockpit.
Thanks to the new FrameFit™ ear seals, the Zulu 4 is ideal for pilots who wear glasses, sunglasses, or headgear. The innovative foam eliminates pressure points and ensures a perfect seal, so you can spend long hours in the cockpit without fatigue. The large ear cavity prevents uncomfortable pressure, while the low-profile stainless steel headband distributes weight so well you’ll hardly notice the headset on your head.
Zulu 4 keeps you going. Connect to two devices simultaneously with dual Bluetooth. Adjust the microphone position precisely to your needs with the extended boom and top-cord design. Stay powered under all circumstances thanks to panel power with AA battery backup. The headset is also fully compatible with the free Lightspeed Aviation iOS app, allowing easy in-flight recording of communications.
