Lightspeed Zulu 4 ANR Headset - Battery Powered (Dual GA Plugs)

What is the Lightspeed Zulu 4 ANR headset and who is it for?

The Zulu 4 is Lightspeed's latest premium Active Noise Reduction headset, built for renters, students, and pilots who fly a variety of general aviation aircraft. This Dual GA Plug version aims for a quieter, clearer, and more comfortable cockpit, improving on the well-loved Zulu 3 with new comfort and audio upgrades.

What is new on the Zulu 4 compared to the Zulu 3?

The Zulu 4 keeps the trusted Zulu performance while adding new FrameFit ear seals for eyewear comfort, Dual Bluetooth so you can pair two devices at once, and enhanced upstream audio for clearer outgoing calls. It retains the proven stainless steel headband and Kevlar-core cable construction along with the 7-year warranty.

Will the Zulu 4 stay comfortable if I wear glasses or sunglasses?

Comfort with eyewear is the headline upgrade. The all-new FrameFit ear seals use tapered foam that molds around eyeglass and sunglass frames, so they do not press into your temples or break the noise seal. The goal is full Active Noise Reduction performance with no pressure points, even on longer flights with sunglasses on.

How effective is the Active Noise Reduction on the Zulu 4?

The Zulu 4 uses award-winning Active Noise Reduction tuned for low-frequency cabin noise like propeller thrum, while its magnesium ear cups help block higher-frequency wind noise. On outgoing transmissions, enhanced upstream audio reduces background noise by up to 90 percent, so your voice reaches ATC and passengers clearly instead of competing with engine rumble.

Does the Zulu 4 have Bluetooth, and what does Dual Bluetooth mean?

Yes. The Zulu 4 features Dual Bluetooth, letting you pair two devices at the same time. For example, you can receive alerts from an aviation app on your iPad while streaming music or taking a phone call. It also includes a wired auxiliary audio input, so you can connect a device the traditional way when you prefer.

What kind of batteries does the Zulu 4 use, and how long do they last?

This Dual GA Plug version is battery powered, running on two standard AA batteries you can find almost anywhere. Lightspeed rates the Zulu 4 for up to 40 hours of life per set, so most pilots get many flights between changes. An automatic shut-off feature powers the headset down when it is not in use to preserve the batteries.

Can this Dual GA Plug version be powered from the aircraft panel instead of batteries?

No. This is the battery powered Dual GA Plug model, designed to run on two AA batteries through its control box. Panel powered operation uses a different connector and is sold as a separate Lightspeed Zulu 4 configuration. If you want headset power drawn from the aircraft, choose that panel powered listing instead of this version.

What plug type is this version, and which aircraft will it fit?

This version uses standard PJ dual general aviation plugs, the twin-plug setup found in most piston aircraft. Lightspeed notes these fit roughly 99 percent of general aviation aircraft, from Cessna 172s to Pipers and Beechcraft. If your aircraft uses a different connector, look for the matching plug configuration, which is offered as a separate listing.

How durable is the Zulu 4, how much does it weigh, and what warranty does it carry?

The Zulu 4 weighs about 14.6 ounces and is built to live in a flight bag, with a stainless steel headband and Kevlar-core cables for everyday durability. It is backed by an industry-leading 7-year warranty, which reflects the confidence Lightspeed places in its construction and long-term reliability for general aviation pilots.

Can I replace the ear seals as a wear item on the Zulu 4?

Yes. The FrameFit ear seals are a soft part that naturally wears over the life of the headset and can be replaced. Refreshing the ear seals periodically helps maintain the noise seal and comfort, keeping the Active Noise Reduction performing the way it did when the headset was new. Replacement seals are sold separately.

Is the Lightspeed Zulu 4 TSO certified?

No, this headset is not TSO certified, which is standard for premium general aviation ANR headsets and not a concern for typical general aviation flying. This particular model ships with dual general aviation plugs intended for fixed-wing piston aircraft. Pilots who need a different connector should choose the matching plug configuration rather than this dual-plug version.
