Noise Cancelling distortions while moving

[adamarceo09]

Good Day Community!
 
I'm new here, and apparently, I'm also new to noise cancelling headphones. I own Sony's h.ear on's which are fantastic cans IMO. Moving on topic; while using these outside while commuting, specifically while riding a bus; while it does its job well by cancelling low freq. background noise, I get these slight nauseating sensations if the ride gets to a bumpy road or any occasion when the headphones move ever so slightly in my head. (by headbanging with the music or just turning my head quickly to name a few). I see that this issue isn't much discussed in the internet. Again, I'm new to NC and I just want to know if this is normal or I should get this replaced immediately. 
 
Thanks!
Adam

It happens to some people. Noise cancelling makes them nauseous so I don't think it's a defective product.

Hi! Thanks for the reply. Anyway, what I'm really curious about if does NC headphones really distort if it moves around your head? As said, if your ride drives into a pothole for example. Mine gives a sharp and discomforting thud when this happens. Another example if that the sound bounce around your ears when you move your head (a bit wildly) with the music?

Well the way noise cancelling headphones work, is it makes a wave opposite to the incoming sound wave (recorded through the internal microphone) in order to cause destructive interference. Now if, for example you hear a loud thud, it is possible that it will create an opposite wave to that and that may be what you are hearing.

I don't quite understand what you mean by this. Can you elaborate?

When NC is on and I start headbanging involuntarily (which happens a lot) the NC seems to react with the movement of my head making the sound uhmm.. It's kind of hard to explain 

 well, the sound it makes is kinda like the sound you hear when you move your hands close-then-far to your ear but amplified. Does that make sense? 

 I'm really having a hard time to explain this, sorry about that xD

Well a possible cause would be that when you're moving your head, the microphone is picking up the air moving around it and translating that into the noise cancellation.

After some research, that seems to be the case. Thanks for the feedback! Happy listening!
