Sound Qualityīose has plenty of experience in the personal audio market. Once you do, you don’t want to go back to any other headset. While this isn’t necessarily something I agree with, it’s fair to say that it can take a bit of time to get used to. Some pilots may even find the A20 is too quiet. The A20 may seem expensive, but when you need to protect your hearing, spending a few hundred more for the A20 over another headset becomes more than worth it. While any pilot should never take their ears for granted, it is pilots who fly day in day out who need the most assurance that they aren’t putting their ears at risk. The A20 is best-in-class at noise cancellation. Sometimes it seems like other brands are playing catch up. It also helps that the company is able to use its vast experience in the personal audio world to design a headset with comfort and sound quality at the forefront of its design. Since then any pilot looking for the best aviation headset doesn’t usually settle for anything less than the A20.

The company designed the first commercial Active Noise Cancellation headset for pilots in 1989.
