Zulu 4 builds on the success of Lightspeed’s best-selling Zulu series ANR headsets to deliver more comfort, clarity,
and flexibility. Dual Bluetooth technology allows seamless connection to multiple devices simultaneously — no
cords, dongles, or constant re-pairing required. Revolutionary FrameFit™ ear seals deliver unrivaled comfort for
pilots who wear glasses, sunglasses or hats. AI-enhanced upstream audio cuts up to 90% of background noise from
outgoing transmissions sent via Bluetooth, so your voice comes through crisp and clear. Additional refinements,
like a 10% longer mic boom, longer upper cable, all contribute to a more flexible,
comfortable headset experience.
Features
• The Lightspeed Aviation App – Connect via Bluetooth to record incoming and outgoing communications,
playback transmissions, draw diagrams, and archive flight recordings onto your phone or mobile device for
post-flight briefing and training.
• Dual Bluetooth® – Connect two devices simultaneously using Bluetooth wireless technology with A2DP en
ables cell phone communications, stereo music streaming, and alerts from aviation apps.
• Low-Profile Comfort – Weighing just 14.9 ounces (including ear seals, head pad, and mic boom), Zulu 4 has
a low-profile, stainless-steel headband that follows the curve of the head for more comfortable distribution of
weight and side pressure.
• High-Performance Fit – Our innovative FrameFit™ performance ear seals are designed with tapered foam to
better seal around eyeglass or sunglass frames, for unrivaled comfort and clarity no matter what you wear. Cup
cavities allow the entire ear to fit comfortably inside.
• AI-enhanced outgoing audio – Automatically cut out up to 90% of background noise from outgoing transmis
sions sent via Bluetooth.
• Durability and Longevity – Made almost entirely of stainless steel and magnesium with durable cables built
around a Kevlar core, Zulu 4 is designed to endure the harshest flying environments and last for years to come.
• Superior Quiet – Zulu 4 delivers advanced active noise reduction (ANR) performance over a deep, broad
range of low-frequency noise. The magnesium ear cups are superior at blocking out high-frequency noise.
• Clear Comms – The Dual Aperture Disc microphone provides greater noise cancellation for clearer, more intel
ligible communications. Exclusive, user-adjustable mic gain helps balance loud and soft voices in a multi-head
set environment.
• ComPriority™ – Never miss important radio communications with patented ComPriority, which automatically
lowers the volume of any auxiliary device during radio or intercom transmissions. The soft mute feature gently
eases music back in for a smooth listening transition.
• Auto Shutoff™ – Lightspeed’s proprietary Auto Shutoff feature saves battery life by automatically shutting
down the headset power when not in use
