Some important points missed for the Audio Technica ANC-7 - and probably for other headphones reviewed to....
1) the ANC-7s are a single detachable cord design - more convenient
2) Can be driven by an iPod without turning on the noise cancelling (Can't do this with the Bose 'Winners' - no power, no sound). However, it is quieter because the impedience is much higher when unpowered - so turn up the volume.
3) Powered by single AAA battery, so no need to worry about rechargable. Changed the battery twice in 12 months ownership.
4) Carry case provided, it's not just a simple floppy bag, so offers reasonable protection
5) There is a lot of noise leakage for those around you on the ANC-7s which might not make you popular on a flight.
6) If you're worried about being deafened by announcements on flights then get a noise attenuator. I got one with my Ultimate Ears Super-fi 5 pros and it works well at protecting your hearing. Presumably you can get them elsewhere. Or if you can cope with Canalphones just the UE5s; up to -27dB noise cancellation (allegedly!).
I have ANC-7s and ruled out the Bose because - they stop working if the battery dies. They are too bass heavy - I prefer a natural sound. They're much more expensive. Subjectively they didn't seem to be that well built. I wanted over the ear headphones, not on-ear. They rely on rechargable batteries rather than simple disposables and I don't want to carry *another* charger around. Bose refuse to publish technical information on their products, whereas I want to see the numbers and pretty graphs :)
I suspect there is much omitted from the other reviews to save space. If you want Bose you could do worse than visit their outlet stores, e.g. McArthur Glen near York. Try before you buy - I did having been convinced by reviews like this I would buy Bose, and bought the ANC-7s instead.
