Lightspeed Zulu 3 Review (Updated October 2026)
The Lightspeed Zulu 3 is an ANR headset with Bluetooth, a wired AUX input, and a 7-year warranty, listed at $949. Two AA batteries are rated up to 40 hours, with less time if you use Bluetooth heavily. It is the best overall pick on this site. It does not have a certified NRR.

Verdict. The Zulu 3 is the best overall headset in this comparison for pilots who want ANR and Bluetooth without the Bose A30 price. It is the wrong spend for a student who only needs a passive trainer headset.

The Zulu 3 is the headset this site names best overall. That means the best balance of active noise reduction, Bluetooth, warranty, and price for a pilot who flies beyond primary training. It does not mean Lightspeed won a lab test we conducted.
Specs that hold up on the manufacturer pages
Lightspeed lists the price at $949 and the weight at 14.6 ounces including ear seals and the mic boom. The construction notes call out a stainless headband, magnesium ear cups, and cables with a Kevlar core. ANR is described across low frequencies, with the cups handling higher frequencies. The user guide's hard number is ANR maximum SPL greater than 125 dB at 100 Hz. There is no certified NRR on that page. This review does not invent one.
Bluetooth is built in. A control-box auxiliary input is there for a wired device. ComPriority lowers auxiliary audio during a transmission. FlightLink, Lightspeed's iOS recording app, uses the included patch cable. Auto shutoff turns the headset down after you take it off. The included kit has patch cords, two AA batteries, and a case. Configurations are dual GA battery power (PN 4064), LEMO panel power (PN 4065), and U-174 (PN 4069). The warranty is 7 years for the original purchaser, with a 30-day return on Lightspeed's own terms.
The user guide is specific about batteries: alkaline or lithium AA cells, not a mix, and rechargeables are not recommended. Up to 40 hours is the ceiling, not the Bluetooth-on promise.
Who should buy it
Private pilots, instrument pilots, and instructors who fly enough to care about fatigue should price the Zulu 3 before the A30. The comparison has the battery and warranty split. Instructors have their own page, and the Zulu 3 wins it.
Helicopter pilots should order PN 4069, not assume a dual-GA box will fit. That constraint is on the helicopter guide.
Who should not
A student who needs a first headset should look at the KA-1 or the H10-13.4. The KA-1 is passive only, with no ANR and no Bluetooth, and it costs $224.95. Spending $949 before you know you will finish training is a choice, not the default.
Pilots who want David Clark's hybrid ANR and Bluetooth should read the DC ONE-X review. The ONE-X lists around $1,020 at Aircraft Spruce, with a 5-year warranty, so the Zulu still leads on price and warranty length inside that pair.
Questions pilots ask
How long does the Zulu 3 battery last?
Lightspeed's user guide says a set of AA batteries can provide up to 40 hours, and that heavy Bluetooth use can reduce that significantly. The low-battery light still leaves about 5 to 10 hours.
Does the Zulu 3 have Bluetooth?
Yes. It also has a wired auxiliary input and ComPriority, which ducks that audio for radio and intercom.
Zulu 3 or Bose A30?
Choose the Zulu 3 to save about $350 and gain two years of warranty. Choose the A30 for three ANR modes and a 45-hour battery rating with Bluetooth off. Neither publishes a certified NRR.
What is the Zulu 3 warranty?
Seven years. The Bose A30 warranty in this comparison is 5 years. The Zulu 3 lists at $949.
Does the Zulu 3 have a certified NRR?
No. Lightspeed publishes an ANR maximum SPL greater than 125 dB at 100 Hz, which is not a certified NRR. The list price is $949.
Will the Zulu 3 plug into a helicopter?
Only the U-174 configuration, part number 4069. The dual-GA model, part number 4064, fits the usual light-trainer jacks. The main list price is $949, and the helicopter SKU price can differ.
How much does the Zulu 3 weigh?
14.6 ounces, including the ear seals and the mic boom. It runs on two AA batteries unless you buy the panel-power version. The list price is $949.
