For over a decade, the Bose A20 Aviation Headset set the gold standard for pilots, earning a massive fan base for its amazing sound quality and durable design. However, Bose has officially discontinued the A20 to make way for its successor, the Bose A30 Aviation Headset.
While the A30 is now the current model, the A20 retains a legendary status within the aviation community. Many pilots still use it, and it remains a popular choice on the used market.
In this review, we'll explore the factors that contributed to the A20's enduring appeal and why its DNA lives on in the new A30.
Noise Reduction and Comfort
One of the best features of the Bose A20 was its outstanding noise reduction capabilities, boasting a 30% improvement over previous aviation headsets of its time. Completed with excellent Active Noise Reduction (ANR), Bose headsets create a peaceful flying experience for both long and short flights.
The A20 was designed with meticulous attention to detail, weighing just 12 ounces. The new Bose A30 builds on this legacy with a refined design that features 20% less clamping force than the A20, maintaining that plush comfort for even longer hauls.

Smart Operation and Customizable Audio
Managing your in-flight audio experience was always easy with the Bose A20. The headset featured a control module that allowed for effortless navigation, while an auxiliary audio input and intercom/AUX priority switching made it simple to incorporate external devices like GPS and traffic warning systems.
With customizable audio prioritization controls, pilots could adjust between "mute" and "mix" settings. The new A30 takes this a step further with a toolless, side-swappable down cable and three selectable modes of active noise cancellation.

Technical Specifications and Versatility
The Bose A20 was an impressive piece of technology, and the A30 continues that tradition. Here is what made the A20 series so reliable:
- Active Noise Cancelling and Bluetooth Feature: Noise reduction capabilities, active equalization, and Bluetooth connectivity made it the top choice for aviation headsets.
- FAA TSO and E/TSO-C139: It received FAA TSO and E/TSO-C139 certifications, proving its high standards of safety and quality.
- Comfortable Communications: With a state-of-the-art microphone and speaker setup, communication is crystal clear even in the most challenging cockpit environments.
- Versatile Connectivity: The headset's versatility is evident in its compatibility with various aircraft plugs, such as dual GA, LEMO (6-pin), and U174 connectors for helicopters.
Reliability and Warranty
Bose stands behind their aviation headsets with an impressive 5-year warranty, giving pilots peace of mind. While the A20 is no longer manufactured, Bose continues to support the product. The new A30 is designed with even greater durability and updated materials to withstand the rigors of the cockpit.
