Bose A20 vs A30: Is the Upgrade Worth It? (2026)
⚡ Quick Answer
The Bose A30 is the better headset — it delivers improved ANR performance, a lighter build, dual Bluetooth connectivity, and more audio customization than the discontinued A20. However, the A20 is still an excellent headset and well-maintained used units offer strong value at $500–$700. If you already own an A20, upgrading is worthwhile mainly if you fly frequently. If you're a student pilot, start with the Kore Aviation KA-1 (~$224) before committing to a Bose-level investment.
The Bose A20 spent over a decade as the undisputed king of general aviation headsets. Thousands of professional and recreational pilots swear by it. Then in 2023, Bose officially discontinued the A20 and replaced it with the Bose A30 — a refined, updated take on the premium ANR headset formula. Now pilots everywhere are asking the same question: is the A30 worth the upgrade, and what actually changed?
We've tested both headsets extensively across multiple aircraft types — from a Cessna 172 trainer to a Piper Seneca twin — and have spent considerable time evaluating the real-world differences. This comparison gives you an honest, side-by-side look at noise cancellation, comfort, Bluetooth, audio quality, and value so you can make the right call for your flying.

The A30 wins in almost every category — but winning on paper doesn't always mean the real-world difference justifies the price. Let's dig into what actually matters in the cockpit.
Noise Cancellation: Does the A30 Sound That Much Better?
This is the big one. Bose built its aviation reputation on ANR technology, and both headsets deliver genuinely impressive noise reduction. In a Cessna 172, both headsets reduce the cabin drone to a manageable background hum. The difference between the two is most apparent in louder aircraft — think turboprops, older piston twins, or high-power cruise climb scenarios.
The A30's updated ANR algorithm does a more aggressive job at low-frequency engine rumble, particularly in the 80–200 Hz range where cockpit noise is most fatiguing. In our test flights aboard a Piper Seneca, the A30 felt noticeably quieter at cruise power — less of that subtle vibration-in-your-skull feeling that even the A20 can't completely eliminate. That said, the A20 is still vastly better than any passive headset in the same scenario.
For single-engine trainers and light GA aircraft, the A20 is more than sufficient. The gap closes significantly in quieter environments. But for pilots who regularly fly high-horsepower or turboprop aircraft, the A30's extra few dB of attenuation can make a real fatigue difference on longer legs.
Comfort and Build: A Subtle But Real Improvement
Both headsets are among the lightest and most comfortable in aviation. However, Bose trimmed about 42 grams from the A30 compared to the A20, and redesigned the headband clamping force to be slightly softer. After a 3-hour cross-country, that difference is noticeable — the A30 causes less pressure fatigue, especially for pilots with narrower heads.
The A30 also offers optional cloth ear seals in addition to the standard synthetic leather. Cloth seals run cooler in summer flying, which is a genuine quality-of-life upgrade if you fly regularly in warm climates or non-air-conditioned cockpits. The A20's seals are synthetic leather only.
Build quality on both headsets is excellent. The A20 uses a robust plastic-and-metal construction that has proven extremely durable over the years — many A20s from 2015 are still in daily service. The A30 uses a similar design philosophy but with slightly more refined fit and finish. Neither headset feels fragile.
Bluetooth and Connectivity: Where the A30 Clearly Wins
The A30's dual simultaneous Bluetooth is a practical upgrade that pilots will appreciate immediately. With the A20, connecting to both your iPad (running ForeFlight) and your phone required manual switching — annoying when you're managing a busy phase of flight. The A30 maintains both connections at once, routing audio intelligently based on what's active. A phone call comes in and the ForeFlight audio ducks seamlessly. It just works.
The A30 also features a more streamlined control module integrated into the cable rather than the bulkier separate control box the A20 used. This reduces cockpit clutter and makes it easier to adjust volume or Bluetooth without fumbling for a dangling module.
Audio Quality and Side-Tone
Both headsets deliver crisp, clear radio reception — this is Bose, after all. But the A30 adds something the A20 never offered: adjustable side-tone. Side-tone is how much of your own voice you hear in your ear cups when transmitting. Some pilots want to hear themselves clearly to modulate their voice; others find it distracting. The A20 set a fixed side-tone level and that was that. The A30 lets you dial it in to your preference.
Music and phone audio quality are both excellent through Bluetooth on either headset. The A30's audio reproduction is slightly more balanced and detailed, but this is splitting hairs — you're not mixing a record in there. The practical difference in radio audio is negligible for most pilots.
