The Bose A30 represents the pinnacle of aviation headset technology. Released in 2023 as the successor to the legendary A20, this flagship headset combines Bose’s decades of acoustic engineering expertise with cutting-edge features designed specifically for pilots. After extensive testing across various aircraft types and flight conditions, here’s our comprehensive assessment of whether the $1,449 price tag is justified.
First Impressions and Build Quality
Unboxing the A30 immediately reveals Bose’s attention to detail. The headset arrives in a premium carrying case with dedicated compartments for the headset, cables, and accessories. The construction feels substantial yet remarkably light—a testament to Bose’s engineering prowess in material selection.
The ear cups feature a new sheepskin leather option (standard is synthetic protein leather) that feels noticeably more premium than previous generations. The headband padding has been redesigned with a dual-layer foam system that distributes pressure more evenly across the skull, addressing one of the few complaints about the A20.

Noise Cancellation Performance
The A30’s standout feature is its three-mode ANR system—a significant upgrade from the A20’s single-mode operation. Here’s how each mode performs:
High Mode: Maximum noise cancellation for loud cockpit environments. Ideal for older piston aircraft, helicopters, and any situation where engine noise is overwhelming. In our testing in a Cessna 172 with the windows cracked, High mode reduced perceived noise by approximately 30 dB—enough to make normal conversation possible without raising your voice.
Medium Mode: Balanced noise reduction that maintains situational awareness. Perfect for most GA flying where you want quiet comfort but still need to hear engine sounds that might indicate problems. This became our default mode for cross-country flights.
Low Mode: Minimal ANR for quiet cockpits or when you want to hear more ambient sound. Useful in modern turboprops or jets where baseline noise is already manageable, or during ground operations when you need to hear ground crew.
The ability to switch modes mid-flight is genuinely useful. During engine runup, we’d switch to High mode. During cruise in smooth air, Medium provided the perfect balance. The toggle on the right ear cup makes switching intuitive without looking.
Comfort: The 8-Hour Test
We deliberately tested the A30 on an 8-hour cross-country flight (with fuel stops) to evaluate long-term comfort. The results were impressive:
- Hours 1-3: Virtually unnoticeable on the head. The 12.3 oz weight is genuinely remarkable.
- Hours 4-6: Still comfortable. No pressure points developing on the crown or around the ears.
- Hours 7-8: Slight awareness of the headset, but no pain or strong desire to remove it.
For comparison, most passive headsets become uncomfortable around hour 2-3, and even competing ANR headsets typically cause some fatigue by hour 5. The A30’s combination of light weight and pressure distribution is class-leading.
The clamping force is firm enough to seal properly against glasses (tested with Ray-Ban Aviators and prescription glasses) without causing temple pain. Bose clearly invested significant R&D into the headband geometry.
Audio Quality and Bluetooth
The A30’s Bluetooth 5.0 implementation supports simultaneous connection to two devices—connect your phone for calls and your iPad for ForeFlight audio alerts. The audio mixing is seamless; incoming calls automatically lower music volume and intercom audio takes priority over everything.
Audio quality for music is excellent by aviation headset standards, though don’t expect audiophile performance. The frequency response is tuned for voice clarity, which means music sounds slightly midrange-heavy. That said, it’s more than adequate for podcasts, audiobooks, or background music during cruise.
The sidetone (hearing your own voice) is well-calibrated and adjustable through the Bose Connect app. Proper sidetone is crucial for avoiding the “talking into a void” sensation that causes pilots to unconsciously raise their voice.
Microphone Performance
The A30’s electret microphone delivers clear, intelligible transmissions in all conditions tested. ATC communications were consistently rated as clear by controllers, even in noisy cockpit environments. The noise-canceling microphone does an excellent job of rejecting background noise while capturing voice.
We tested microphone performance in:
- Cessna 172 at full power during runup: Clear transmissions
- Piper Cherokee with door seals in poor condition: Clear transmissions
- Open-cockpit biplane (borrowed for testing): Surprisingly usable transmissions
Real-World Usage Scenarios
Weekend Warrior ($100 Hamburger Flights)
For recreational pilots flying 2-4 hours at a time, the A30 transforms the flying experience. Fatigue reduction is dramatic—you’ll land feeling noticeably fresher than with a passive headset. The price is harder to justify for infrequent flyers, but if flying is your primary hobby, it’s a worthwhile investment in enjoyment.
Cross-Country Cruising
This is where the A30 truly shines. Long flights that would be exhausting with lesser headsets become almost relaxing. The combination of effective noise cancellation, light weight, and all-day comfort makes 4-6 hour legs much more tolerable. Business pilots who fly themselves will find the A30 pays dividends in reduced fatigue.
Flight Training
Student pilots and instructors benefit enormously from ANR. Better hearing = better learning. However, the A30’s premium price may be difficult to justify for a student who might fly 50-100 hours total during training. Consider starting with a Faro G3 ANR or used A20, then upgrading once you’ve earned your certificate and know you’ll continue flying.
Helicopter Operations
The A30 is available with a U-174 helicopter plug, and its strong noise cancellation handles the unique frequency profile of helicopter noise admirably. Rotorcraft pilots report significant fatigue reduction compared to passive headsets commonly used in the industry.
Comparison to Competitors
Bose A30 vs. Lightspeed Zulu 3
The Zulu 3 ($899) offers approximately 90% of the A30’s noise cancellation at 62% of the price. For most pilots, the Zulu 3 is the smarter financial choice. However, the A30’s selectable ANR modes, lighter weight (12.3 oz vs 12.8 oz), and superior comfort justify the premium for frequent flyers or those who prioritize having the absolute best equipment.
Bose A30 vs. Bose A20
If you’re upgrading from an A20, the improvements include: lighter weight, selectable ANR modes, improved Bluetooth with dual device pairing, and better comfort. Whether these justify the upgrade cost depends on how much you fly and whether your A20 still functions well.
Bose A30 vs. David Clark ONE-X
The ONE-X ($895) offers legendary David Clark durability and the best battery life in the industry (50+ hours). Its hybrid ANR continues working in passive mode if batteries die. However, the A30’s noise cancellation is noticeably superior, and the weight difference (12.3 oz vs 12.3 oz) is negligible. Choose the ONE-X for durability, the A30 for noise cancellation.
