More Comfort
All new FrameFit™ ear seals are a game changer for pilots who wear glasses, hats, or sunglasses. The innovative tapered foam is designed to better seal around headwear to minimize pressure points, maximize performance, and offer unrivaled comfort no matter what you wear. Zulu series signature large cup cavity encompasses the entire ear, to prevent pain caused by seals pressing against the edge of the ear. Low-profile stainless steel headband follows the curve of the head for more comfortable distribution of weight and side pressure.


More Flexibility
Thoughtful refinements allow you to customize your headset experience like never before, keeping you unencumbered in the cockpit. Connect to two devices simultaneously with Dual Bluetooth. Tweak headset placement to your exact preferences with a 10% longer mic boom and longer upper cable. Stay connected via a flexible power supply for panel-powered headsets with AA battery backup

Zulu 4 is compatible with the Lightspeed Aviation App, our free in-flight cockpit recording application for Apple iPad and iPhone.
