Comparison
Bose A30 vs Lightspeed Zulu 3 (Updated October 2026)
Buy the Bose A30 if you want three ANR modes and Bose's battery rating of at least 45 hours with Bluetooth off. Buy the Lightspeed Zulu 3 if you want ANR and Bluetooth for $949, which is $350 less, with a 7-year warranty instead of 5. Neither company publishes a certified NRR, so this is not a measured noise ranking. Student pilots usually do not need either headset yet.

Both headsets are current ANR flagships with Bluetooth and a wired audio input. The decision is price, warranty, battery rating, and whether you want Bose's three modes. It is not a decision this site can settle with a decibel meter we do not own.
Price and warranty
Bose lists the A30 at $1,299 with a 5-year limited warranty. Lightspeed lists the Zulu 3 at $949 with a 7-year limited warranty. The $350 gap is the whole argument for the Zulu if the airplanes you fly are ordinary GA singles and twins. The argument for the A30 is the feature list below, not a claim that it will last longer on paper.
Full write-ups: Bose A30 review and Lightspeed Zulu 3 review.
Noise reduction, stated carefully
The A30 owner's guide lists full active noise reduction up to 115 dB SPL and a reduced range up to 134 dB SPL. Bose sells three user-selectable ANR modes and a talk-through control. The Zulu 3 user guide lists ANR maximum SPL greater than 125 dB at 100 Hz. Those are different measurements. Putting both in a column called "30+ dB NRR" would be false, so this page does not do that.
Battery and Bluetooth
The A30 runs at least 45 hours on two AA alkaline batteries in typical aircraft noise, and 25-plus hours with Bluetooth used continuously. The Zulu 3 user guide says a set of batteries can provide up to 40 hours, and that heavy Bluetooth use can reduce that a lot. Both have auto-shutoff behavior. Both offer panel-power configurations if you do not want to depend on AA cells.
Bluetooth on the A30 is version 4.2. The Zulu 3 adds ComPriority, which lowers auxiliary audio during a radio or intercom transmission, and FlightLink recording on iPhone and iPad through a patch cable.
Fit
Bose says the A30 has lower on-head weight and about 20 percent less clamping force than the A20. Bose lists 404 grams on the head. The owner's guide also lists 12 ounces for the headset alone. The Zulu 3 lists 14.6 ounces including ear seals and the mic boom. If you wear glasses, both companies design the seals around that use. Read the comfort guide and then try the headset if the retailer allows a return. Clamp force is personal.
Students, and the KA-1
A student in a 172 does not need a $949 or $1,299 headset to hear the instructor. The KA-1 at $224.95 is the best passive choice. The H10-13.4 at $375 is the certified, most proven alternative. The P1 at $124.95 is the budget pick. The KA-1 and the P1 are passive only, with no ANR and no Bluetooth. Buy the A30 or the Zulu 3 when the flying justifies active cancellation. The student guide walks through that choice.
Questions pilots ask
Is the Bose A30 quieter than the Lightspeed Zulu 3?
Bose and Lightspeed do not publish a shared certified NRR, so this site does not declare a measured winner. The A30 has three selectable ANR modes. The Zulu 3 publishes an ANR maximum SPL greater than 125 dB at 100 Hz.
Which has the longer warranty, the A30 or the Zulu 3?
The Zulu 3 warranty is 7 years. The A30 warranty is 5 years.
Should a student pilot buy the A30 or the Zulu 3?
Usually neither. The KORE KA-1 at $224.95 is the best passive headset for primary training. The David Clark H10-13.4 is the certified alternative. The KORE P1 is the budget pick. The KA-1 and the P1 have no ANR and no Bluetooth. Buy a flagship ANR headset when you know you will keep flying.
Does the Zulu 3 have Bluetooth?
Yes. It also has a wired AUX input, and the list price is $949. Heavy Bluetooth use reduces the up-to-40-hour battery rating.
Does the A30 publish a certified NRR?
No. Bose does not publish a certified NRR for the A30, and Lightspeed does not publish one for the Zulu 3. The A30 lists at $1,299.
What plugs do the A30 and the Zulu 3 use?
Both are sold with dual GA plugs, and both offer other aircraft connectors. The Zulu 3 dual-GA list price is $949. Order the plug the airplane actually has.
