Bose A30 vs A20: Which Aviation Headset Should You Buy?

Quick answer: Choose the Bose A30 if you fly frequently, want the lightest-feeling Bose over-ear aviation headset, or value adjustable active noise reduction. Choose the Bose A20 if you find legitimate new-old-stock, renewed, or used inventory at a meaningful discount. Both are capable premium headsets, but condition, connector type, warranty coverage, and total cost matter more with the older A20.

Bose A30 and A20 at a glance

Why the Bose A30 is our premium pick

The A30 is the safer recommendation for a pilot buying one headset to use for years. Its adjustable active noise reduction lets you change how much outside sound reaches you, while the lighter-feeling fit helps during long cross-country flights. Bluetooth is useful for phone calls on the ground, audio alerts, and compatible electronic flight bag workflows. It should never replace monitoring the radio or following cockpit procedures.

The common dual-plug general-aviation version is appropriate for many piston aircraft, but not every cockpit. Verify whether you need dual GA plugs, a six-pin LEMO connector, an XLR connector, or a helicopter plug before ordering. A premium headset with the wrong connector is an expensive inconvenience.

Why the Bose A20 still deserves consideration

The A20 built its reputation over years of general-aviation and professional use. Many pilots already know its controls, replacement accessories are widely discussed, and a well-maintained unit can remain a serious cockpit tool. The key is buying it for the right reason: value.

Because the A20 is the older model, do not assume every listing represents current factory-new inventory. Read the seller description carefully. For used or renewed units, inspect the control module, cable strain relief, microphone boom, ear cushions, headband pad, battery compartment, and included plugs. Ask whether Bluetooth is included because configurations vary.

Noise reduction and radio clarity

Both models are designed to reduce the steady low-frequency noise common in piston-aircraft cabins. That can reduce fatigue and make radio calls easier to understand, especially on longer legs. No headset eliminates the need for disciplined radio technique. Correct microphone placement, proper squelch settings, a good ear seal, and a functioning aircraft audio system all affect clarity.

The A30 adds adjustable ANR modes. That flexibility can be helpful when a pilot wants maximum quiet or needs more awareness of conversation in a particular cockpit. The A20 remains impressively quiet, which explains why many owners see no urgent reason to replace a functioning unit.

Comfort on long flights

Comfort is personal, but clamping pressure becomes noticeable after several hours. Glasses, hat style, head shape, and ear-seal condition all change the experience. The A30 is generally the better starting point for pilots sensitive to pressure. A discounted A20 may still be the smarter purchase if you already know its fit works for you.

If possible, wear either headset for more than a quick showroom test. Look for pressure at the temples, broken ear seals around glasses, microphone drift, and hot spots on the headband.

Which connector should you buy?

• Dual GA plugs: common in Cessna, Piper, Beechcraft, and many training aircraft.
• Six-pin LEMO: can draw aircraft power in compatible installations and may reduce battery dependence.
• U-174 helicopter plug: used in many helicopter applications.
• XLR configurations: found in some professional and airline environments.

Do not choose solely from the product photo. Match the exact connector to the aircraft or audio panel you will actually use.

When the A20 is the better buy

• You find a reputable listing at a substantial discount.
• You already own A20 accessories or know the fit works for you.
• You can verify the unit’s condition and return policy.
• You fly enough to benefit from ANR but cannot justify the A30’s current price.

When the A30 is worth the upgrade

• You regularly fly two-hour or longer legs.
• You are buying new and want current-generation support.
• Lower clamping pressure is important to you.
• You want adjustable ANR and a premium long-term headset.

Verdict

For most pilots buying new, the Bose A30 is our recommendation. The A20 is not obsolete as a cockpit tool; it is a value play. Buy the A30 for the current design, comfort, and lower purchasing uncertainty. Buy the A20 when the discount compensates for its age and you can verify configuration, condition, and warranty.

Before ordering either model, confirm connector type and compare the final delivered price, seller, return policy, and included accessories.
