The world's quietest aviation headset actively conforms to your ears, your environment, and your preferences to deliver stunning clarity, quiet, and audio quality. The winner of the 2014 Flying Magazine Editors' Choice Award and a 2015 CES Innovation Award Honoree, Zulu PFX is packed with innovations designed to make flying safer and more enjoyable.
One-of-a-kind personalization technology —
Streaming Quiet™ ANR continuously adapts to your environment, extending the amount, consistency, and frequency range of noise cancellation.
Acoustic response mapping measures your unique auditory landscape, personalizing the audio response for maximum noise attenuation, voice clarity, and music fidelity.
Customized audio is available through enhanced capabilities in our FlightLink app, which allows you to configure and save key audio and other settings to personal profiles.
Comfort — Based on the LightComfort™ design made famous by Zulu.2, Zulu PFX features a head-friendly 13.9 ounces, exceptional fit, and plush ear seals that provide 20% more surface area and 30% more space for your ear inside the ear cup than its closest competitor for a better seal and more comfortable distribution of side pressure.
Durability — Rugged cables, constructed of silver-coated copper alloy wrapped around a Kevlar core, deliver extraordinary flexibility, strength, and audio quality.
Full Bluetooth® Integration — Enjoy excellent call clarity, music fidelity, and wireless access to critical audio alerts from aviation apps on mobile devices.
Enhanced FlightLink capabilities — With Zulu PFX, FlightLink not only seamlessly captures cockpit communications for instant playback or later retrieval, allowing you to set a variety of personal audio and operational preferences.
Music fidelity — The Front Row Center™ feature is enhanced by advanced digital processing, creating remarkable, concert-class fidelity and a simulated 360-degree music experience.
Auto Shutoff™ — In Zulu PFX, Lightspeed's proprietary Auto Shutoff feature is enhanced with increased sensitivity, saving even more battery life by automatically shutting down the headset power when not in use.
Cell phone / music connection — The integrated control box auxiliary input for connecting a cell phone, music player or other audio device now has controls for bass, treble, and intercom priority, thanks to the enhanced capabilities in FlightLink.
Stereo or mono — Match audio panel inputs with a quick switch to stereo or mono using the new, easy-to-access external switch.
Firmware upgradability — Firmware updates are just a download away, giving Zulu PFX unlimited potential to evolve with new software innovations.
