True "noise cancelling" mics sound awful. They work on the principle of
cancelling noise more than an inch or two from the mouth. SUPER noisy
places like aircraft are the ONLY place to use them.
Most hams who have too much background noise either don't work the mic
close enough (it should be an inch or two above and alongside the
mouth), or have processing and/or mic gain turned up way too high.

Just curious ... I inherited a David Clark noise cancelling aviation
headset/mic from a neighbor who was a US Forest Service pilot. I've
never tried it, the connector is strange. I'm not even sure I know
where it is right now. Will it work with my K3 if I can find it and
get the connector compatible? I know they're expensive.
Maybe it will cancel the powerline noise on 80? [:-))

Although headsets like my Heil Pro 7 may be more money, am I really
"wasting" money on buying a "fancy brand name" considering the
unit consists of mic and incredible speakers?
Yes, at about $250 retail (plus adapter cable), the Pro 7 is more than
five times as expensive as the Yamaha CM-500 (electret mic), Koss SB40
(dynamic mic) or SB45 (electret mic) headsets. Both the Yamaha and
Koss headsets have outstanding 120 Ohm headset drivers with sensitivity
rated at 96dB/mW and microphones well tailored for voice work. Heil
does not even publish the impedance or sensitivity for their headset
drivers!
For the price of a Heil Pro 7 one could get a Broadcast headset like
the Audio Technica BPHS1 ($199), Sennheiser HMD280 ($249) or Shure
BRH440M ($249) - all of which are significantly higher quality than
the Pro7 (and field proven).
