I'm on my third pair of noise cancellers. The problem with NC phones is
that, though they were very well on repetitive, low-frequency noise, e.g.
the roar of the jets and the rush of the air against the hull, they don't
attenuate sound in the frequencies of human speech (or baby crying). In
fact, they almost make it worse as they eliminate the white noise which
normally could cover it a bit. However, I use mine with a good headphone
amplifier and an MP3 player; listening to music at the
not-so-loud-that-it's-painful-but-still-fills-your-head level helps block
out almost everything.

I would agree with this advice. I use a NoiseBuster set, which I do find
helps reduce the tiring background noise on long trips, but it doesn't
cancel out intermittent noise such as conversation or announcements.
