Which Headset Is Right for You?
In September 2022, Lightspeed Aviation introduced the Lightspeed Delta Zulu and Bose followed with the A30 in the Spring of 2023, prompting questions about direct comparisons. For parity with Bose’s lineup, this article compares Lightspeed Zulu 3 with the Bose A30 across seven factors most pilots care about: Quiet, Comfort, Craftsmanship & Features, The Company, TSO, Price, and Warranty.
How Quiet Are They?
Both headsets deliver comparable active noise reduction (ANR) and clear audio in typical GA and business aviation cabins. The A30 offers three modes for noise cancelling (low/medium/high); pilot feedback generally favors keeping the noise cancelling on the quietest setting while in GA aircraft. Because of this, the Zulu 3 only offers the highest level of noise cancelling in their headsets.
The microphone noise cancellation is excellent in both headsets, employing electret noise canceling capability. The fidelity of the communications is excellent in both headsets for ATC, and both provide very high music fidelity.
Comfort Over Long Flights
Comfort affects safety and situational awareness. The Zulu 3’s ear seals provide about 30% more surface area and a larger ear opening designed to fit around, not on, your ear. This distributes side pressure more evenly. Having your ear fully inside the cup also reduces hotspots during longer legs.
The A30’s narrower seals may rest on the outer ear for some users. The Zulu 3’s low‑profile stainless headband contours naturally, while The A30 uses a spring‑enabled design tuned to clamp with less force than its predecessor. Fit is personal so you may want to try both on if possible.
Craftsmanship & Features
Both include core conveniences: Bluetooth for calls and music, auto shut‑off, and comm priority. Each headset operates on two AA batteries (typ. 40+ hours of battery life) and supports panel power via single‑plug LEMO in equipped aircraft. The A30 allows swapping the control‑box cable between earcups.
The Zulu 3 features a mainly metal build (magnesium cups and slides, stainless steel headband) and a Kevlar‑reinforced cable that resists kinks. The Zulu 3 also comes standard with FlightLink integration. FlightLink is a free, proprietary app that adds enhanced functionality to the Zulu 3 and Sierra headsets. FlightLink works seamlessly to record and playback incoming and outgoing communications. This is a great added feature for recording training flights, souvenir and sentimental flights, and for instant playback of ATC calls in real time.
The Company: Focus & Community
Lightspeed’s vision is to create products that protect and save lives. We create products that are designed by pilots for pilots and focus solely on general aviation. Because of that, we know more about what pilots need today and how to anticipate what pilots will need in the future.
Lightspeed’s agility allows us to drive innovation and introduce features and upgrades long before competitors. Examples of these include innovative features include Auto-Shutoff™, ComPriority™, conformal foam ear seals, AA/rechargeable battery power, integrated apps and more.
Many of these innovations are now commonplace in aviation headsets today but were pioneered by Lightspeed and guided by the company’s understanding of the flight environment
Lightspeed is also dedicated to growing the aviation community and is privileged to pay it forward through numerous philanthropic efforts. Donations have included hundreds of Zulu 3 headsets through the Ray Scholars program with EAA, years of donations to the EAA Young Eagles, AOPA’s You Can Fly programs, and countless schools, flying clubs and other charitable organizations in general aviation.
TSO: Do You Need It?
While the Bose A30 is TSO‑authorized; the Zulu 3 is not. For GA operations, a TSO headset is not required by the FAA. Certain commercial operators may choose to specify TSO equipment in their manuals, so if your employer requires TSO, choose accordingly. Otherwise, select based on comfort, features, support, and total cost. We go into much more depth in our article, Does TSO Really Matter for Headsets?
Price: as of January 2026
The Zulu 3 is currently listed at $949 USD. The Bose A30 is listed at $1,299 USD, a $350 increase for broadly similar performance and features. Note: prices can fluctuate; check current retail.
Warranty & Support
Lightspeed backs the Zulu 3 with an industry-best 7‑year warranty. Many competitors, including Bose, offer five years or less. Strong warranty coverage can reduce total cost of ownership over time.
Bottom Line & Next Steps
Both the Zulu 3 and A30 are excellent ANR headsets. If you value more, durable metal construction, the ability to record your flights, a longer warranty, and a lower price, the Zulu 3 makes a compelling argument.
