Bose A20 vs A30 – Check Which One Is Best & Why?

Bose A30 & Bose A20 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Bose A30 rather than the Bose A20. 

Why Do I Recommend The Bose A30

  • The Bose A30 features three selectable active noise cancellation modes for customizable noise reduction based on cockpit conditions, whereas the Bose A20 uses a single fixed ANC level.
  • Bose A30 has 20% lower clamping pressure for improved long-term comfort during extended flights, while the Bose A20 applies higher pressure.
  • It comes with a detachable and reversible microphone boom for quick side swapping without tools, whereas the Bose A20 requires service intervention to switch mic placement.
  • The Bose A30 features a thinner and lighter cable design to reduce tangling and improve cockpit mobility, while the Bose A20 uses a thicker and less flexible cable.
  • Bose A30 includes updated Bluetooth functionality for both audio streaming and calls, whereas the Bose A20’s Bluetooth is limited to phone and intercom audio only.
  • The Bose A30 has a slimmer, lighter control module for easier placement and operation in tight cockpit spaces, while the Bose A20 uses a larger and bulkier module.
  • Bose A30 features an advanced digital noise cancellation circuit for smoother and more adaptive sound reduction, whereas the Bose A20 relies on an older analog ANC system.
  • It comes with softer redesigned headband padding and improved earcup sealing to enhance comfort and passive isolation, while the Bose A20 uses an older cushion design.

Maybe the Bose A20 price can make you comfortable because it’s a little bit cheaper than the Bose A30. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
