What makes the A30 Aviation Headset so comfortable?

Overall, the Bose A30 Aviation Headset is one of the smallest, lowest-clamping and lightest around-ear active noise cancelling headsets on the market—it’s a balance of function and comfort without sacrificing stability.The headset’s angled earcups follow the contours of pilots’ heads, and the intentional shape of the headband pads helps achieve the highest level of comfort in the lowest possible on-head weight. Additionally, the A30 has distinct left and right earcups with a quick release and a side-swappable mic for improved comfort and ergonomics.

How much noise reduction does the Bose A30 Aviation Headset provide? What is the attenuation at different frequencies?

The Bose A30 Aviation Headset provides three modes of user-selectable noise cancellation that were individually engineered for specific use cases. “Low” helps optimise interpersonal communication outside the use of an intercom system. “Medium” provides the most consistent amount of reduction across a wide range of frequencies, and “High” provides the most active noise reduction to maximise the signal-to-noise ratio for radio communication. All three modes have been engineered for distinct uses.Bose does not make claims about the mode of noise...

Does the Bose A30 Aviation Headset have volume knobs?

Yes. Similar to the A20, there are left and right sensitivity adjustment wheels on the control module. These can be used to accommodate differential hearing loss and multiple radio inputs in stereo mode or to help users control radio inputs in one ear to hear outside sound sources more clearly. For larger adjustments, volume tuning is typically done on the audio panel or for each radio.
