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 enables 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.
- Clear Comms – AI-enhanced upstream audio cuts up to 90% of background noise from outgoing transmissions sent via Bluetooth®, so your voice comes through as though there is no engine noise at all. The Dual Aperture Disc microphone provides greater noise cancellation for clearer, more intelligible communications. Exclusive, user-adjustable mic gain helps balance loud and soft voices in a multi-headset environment.
- 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.
- 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.
- 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.
- Auto Shutoff™ – Lightspeed’s proprietary Auto Shutoff feature saves battery life by automatically shutting down the headset power when not in use.
- Included Accessories: Your Zulu 4 headset package includes: Zulu 4 ANR headset, Quick Start Guide with warranty information, carrying case, two AA batteries, and cord clip.
