The Bose Killer (am I allowed to say that?)
Coming from a world of soft-shell bags, messy cables dominating the cockpit and passive noise cancelling, I felt a sense of quality and performance from the Zulu 4s from the get-go.
When the time came for me to buy a new ANR headset, I, as most of us did, had worn the same pair of David Clark's for at least five years — only pausing briefly in between to try a pair of A20s.
Comfort has been my greatest challenge, and objective, to resolve in the cockpit. I believe the Zulu 4s, for me, sit right in the midpoint.
In my early training, I was exposed to what almost felt like a Lightspeed "club." Looking around — usually to the right seat — countless times I would see the warm grey ear cups of Zulu 2s and 3s. They are a fan favourite, for many good reasons.
Unzip the hard-shell case and you're greeted by a Kevlar cable, a familiar control module, and a headset that looks much like its predecessor — albeit in black.
Put the Zulu 4s on, however, and things begin to change.
Immediately, I thought to myself: hmm — not too firm, not too loose… just right?
So, Why Not Bose?
I often say to people, it's like trying to buy toothpaste — too many options.
When you're standing in the aviation headset aisle, metaphorically speaking, Bose sits at the top shelf with its name in lights. The A20 is a genuinely excellent headset. Nobody is disputing that. But excellent and right for you are two very different things — and that's where the conversation gets interesting.
The Zulu 4s come in noticeably under the A20's price point. For a headset that delivers comparable — and in some areas superior — ANR performance, that delta matters. Especially for the student pilot scraping together hours, or the seasoned GA pilot who'd rather put that money toward avgas.
Lightspeed's Bluetooth implementation is seamless. The audio quality for music and phone calls is genuinely good — not "good for an aviation headset" good, but good good. The passive attenuation when the battery dies is also reassuring; you're not suddenly flying deaf if you forget to charge.
Battery life on the Zulu 4s is class-leading. We're talking 50+ hours on a set of AAs. Bose's A20 will get you roughly 45. In practice, neither will leave you short on a normal day — but there's something psychologically comforting about knowing you have more runway, so to speak.
A Few Quirks — Let's Be Honest
No headset is perfect, and the Zulu 4s are no exception. A small number of users have reported occasional inconsistencies with the ANR performance in certain acoustic environments — particularly in louder, high-vibration aircraft. There have also been isolated mentions of the control module's Bluetooth connectivity requiring a re-pair after firmware updates, and a handful of reports about the headband adjustment feeling slightly stiff out of the box.
It's worth putting these in context, though. Lightspeed has sold hundreds of thousands of headsets across their Zulu line, used everywhere from Cessna 172 training circuits to Citation jets, bush strips to busy Class D traffic. The number of reported issues, when weighed against that volume and that sheer diversity of use cases, is genuinely low. These aren't systemic failures — they're the kinds of edge cases you'll find in any product at scale.
Lightspeed's customer service reputation, for what it's worth, is one of the strongest in the industry. Their warranty support is frequently cited by pilots as a reason they keep coming back to the brand — and that loyalty says something.
The Verdict
The Zulu 4s aren't trying to topple Bose by being flashier. They're doing it by being smarter — better value, better battery, genuinely competitive noise cancellation, and a build quality that holds up across years of daily flying.
Are they the perfect headset for everyone? No headset is. But for the pilot who wants premium performance without the premium premium price — and who appreciates a bit of understated style in the cockpit — the Zulu 4s make a very compelling case.
The "club" is still going. And honestly? There's a reason.
