Noise cancelling headphones rely on the distance between microphone and
ear being a small fraction of the audio wavelength. At high
frequencies, that will be impossible to achieve, and, even if you put in
a compensating delay, the path to the ear is going to depend on the

I have two pair Bose QC15 and one less costly headphones ($125), all of which
are about three years old. The black coating on every one of the ear piece
cushions has deteriorated and flacked off. The sets work properly and I like
them but I could do without the black poof all over the place.
I also used a QC15 and then moved to the QC25 and found that either is a very
comfortable headset to wear for long periods of time. The little microphone
that “dangles” in the cord actually works quite well with both the K3s and KX3
in most surroundings. All that it requires is a good TRRS
I've used the QC-15 and the are good. I had a headset buddy but the boom
was "limp" it worked. I have a Uflymic for the QC15 if anyone has an
interest.
My choice now is the Bose QC25 and modmic by Antlion. The QC25 has been
replaced by the QC35 so you can get a "25" in an affordable range.
Can anyone point me to a specification for any aviation headset that claims the
microphone has active noise cancellation? Can anyone point me to a
