I don't think noise canceling headphones do much to shut out the
loud-mouthed operator sitting next to you. That does not meet the profile
of "noise". They will cancel white- and pink-noise sounds such as the fans
on amplifiers.

Subject: Re: [CQ-Contest] Noise cancelling headphones
The noise cancellers work great in VERY noisy environments with lots of low
frequency noise. Most are made to attenuate noise by 15-20 dB in the 60-150
Hz region that are generated by propeller driven airplanes. I couldn't live
without mine in the plane, but I don't think they are worth the money or
effort for radio use, unless you have some really loud operators in a M/M...

<< Has anyone had any experience with "noise cancelling" headphones?
I just tried a pair of Sony MDNR5's and they look promising.
I am getting ready for a multi multi operation next year, and
need a set of headphones for a noisey environment. I usually
use one of a couple of pairs of Sennheiser phones that I have,
and they are fine for a relatively quiet environment. I
should mention that these are for cw purposes, and I don't
want to be distracted by the ssb op next to me...
Thanks for the time.
