Bose introduced its long-awaited A20 noise-canceling headset at the EAA AirVenture show in Oshkosh in July and attendees immediately began snapping up the $1,095 (retail) headset. The A20 launch comes 12 years after Bose introduced the Aviation Headset X, spawning keen competition in the headset market and convincing pilots that noise-canceling plus passive sound deadening is the way to fly.

The major improvements on the A20 are not just built-in Bluetooth and auxiliary input but greatly enhanced noise reduction. Whereas the Headset X has one internal microphone inside each ear cup to identify the anti-noise signal required to cancel sound waves, the A20 has microphones inside and outside the ear cup.
These cancel noise in a wider range of frequencies and help cancel ambient noise that the Headset X couldn’t sense.
