Lightspeed Zulu PFX

ANR Headset with Bluetooth


Streaming Quiet™ dynamic ANR continuously adapts to your environment, extending the amount, consistency, and frequency range of noise cancellation.

Acoustic response mapping measures your unique auditory landscape, adapting the audio response to your ear shape and size for maximum noise attenuation, voice clarity, and music fidelity.

Personal preferences can be set using the enhanced capabilities in FlightLInk, the proprietary app developed by Lightspeed for the Apple iPad® and iPhone®. Bass and treble levels of the intercom and auxiliary inputs can be adjusted independently and separate intercom priority options can now be set for Bluetooth and wired input. The voice clarity option boosts frequencies common in human speech without impacting the quality of music from auxiliary devices. In-flight recording is now accomplished through a wireless Bluetooth® connection.


Zulu PFX adapts to your ears through acoustic response mapping. This proprietary technology uses sound waves and advanced signal processing to measure your unique auditory landscape, adapting the audio response to your ear’s size and shape for maximum noise attenuation, voice clarity and music fidelity.


Streaming Quiet™ ANR allows Zulu PFX to adapt to your environment. Streaming Quiet uses ambient microphones to continuously sample cockpit noise before it penetrates the ear cup. An internal microphone placed near the ear canal monitors ANR performance. The microphones feed information to the CPU, a powerful digital processor that analyzes a stream of both the external ambient noise and internal residual noise at a rate of one million times a second and instantaneously creates precise ANR responses customized to your dynamic cockpit sound environment. The result is a dramatic extension in the amount, consistency, and frequency range of noise cancellation—regardless of the aircraft—allowing important communication to come through with amazing clarity and producing music with outstanding fidelity.


In addition to its advanced personalization features, Zulu PFX also leverages the latest technological advances across multiple fields.


Enhanced durability — Rugged cables, constructed of silver-coated copper alloy wrapped around a Kevlar core, deliver extraordinary flexibility, strength, and audio quality.

Upgradeable firmware — Updates are just a download away, giving Zulu PFX unlimited potential to evolve with new software innovations.


Zulu PFX also includes the award-winning comfort and advanced features that have made the Zulu family the choice of pilots around the world—made even better.


Music fidelity — The Front Row Center™ feature combined with rugged cables and advanced digital processing makes the concert-class fidelity even better.

Auto Shutoff™ — In Zulu PFX, Lightspeed’s proprietary Auto Shutoff feature is enhanced, 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 FlightLink app.

Included — Custom molded carrying case, cellphone/music patch cord, cord clip, four AA batteries, foam windscreen.

Available configurations: Battery or panel power models Dual GA, LEMO, or U-174 connectors Straight upper cable
