From a physics perspective two standing waves that are of the same frequency and amplitude but 180 degrees out of phase will cancel each other out to cause 0 noise. So proper noise cancellation (even electronically) shouldn't damage your hearing at all

yeah i am aware of the physics behind it but my point is that just because your ear no longer hears the noise does it mean it is no longer subject to the pressure wave? after all on a plane you still get the popping sensation in your ears.
This is turning into one of those "if a tree falls in a forest" questions lol
Anyway after looking at the guide above it does not do a great job of canceling out wind noise so i am happy with my £5 fix haha :lol

Electronic cancellation of the noise will only occur within the headphones' frequency range. Very low frequencies will be outside that range... unfortunately the noise produced by air thundering across the base of a crash helmet at 90mph does contain a lot of very low frequencies.
Then again, earplugs have a hard time filtering those out too.

Of course, but the cancellation technology is cancelling out noise. The fact that it can't cancel out frequencies out of its range bears no impact since without the tech you would be exposed to them regardless. I was mostly pointing out that using the technology wouldn't cause any additional noise on your ear and would in fact reduce it.

Also the reason for your ears popping on a plane isn't the noise, its the altitude and pressure. Noise cancellation for headphones will decrease pressure (due to cancelling the waves) - at least within its capable range
