The Lightspeed Zulu 4 is the next evolution in one of aviation’s most celebrated headset lines. Designed for pilots who demand uncompromising performance, refined comfort, and cutting-edge technology, the Zulu 4 sets a new benchmark for premium ANR headsets.

More Comfort, More Freedom

FrameFit™ Performance Ear Seals: A breakthrough for pilots who wear glasses or sunglasses. Tapered foam creates a superior seal without pressure points, ensuring clarity and long-lasting comfort.
Spacious Cup Cavities: Encompass the entire ear, eliminating the discomfort caused by seals pressing against the ear’s edges.
Low-Profile Headband: Lightweight stainless steel design follows the natural curve of the head for balanced weight distribution, even on extended flights.
Feather-Light Build: At just 14.6 oz., the Zulu 4 remains one of the lightest full-featured premium ANR headsets available.

More Clarity, More Connection

AI-Enhanced Upstream Audio: Reduces background noise by up to 90% in outgoing transmissions, ensuring your voice is delivered cleanly over Bluetooth® or ATC frequencies.
Dual Aperture Disc™ Microphone: Advanced noise cancellation technology for crystal-clear communication in every environment.
Front Row Center™ (FRC) Audio: Exclusive cross-feed stereo technology delivers music fidelity and communication clarity unmatched by conventional aviation headsets.
User-Adjustable Mic Gain: Balance voice levels across multi-headset cockpits for consistent, professional communication.

More Flexibility, More Control

Dual Bluetooth® Connectivity: Connect two devices simultaneously—seamlessly integrate your smartphone, tablet, or aviation apps.
Refined Ergonomics: Extended mic boom and longer upper cable for customizable headset positioning.
Power Without Compromise: Operates via two AA batteries, with the option of panel power when supported in helicopter installations.
ComPriority™: Prioritizes critical radio transmissions by lowering auxiliary audio—then smoothly restores music or app alerts.
Auto Shutoff™: Preserves battery life by automatically powering down when not in use.
