Here we have the NoiseHush i7 Noise Cancelling headphones.
Soundstage - Pretty congested. Not the worst I've heard, but there isn't really any space in the presentation still.
Noise Cancelling ON - The sound becomes much different once the NC feature is on. Whether it is better or worse is solely your opinion. In my opinion, I don't like the sound as much as I do when NC is off.
I personally feel that it loses any sense of transparency that it may have had in the 'off' position. It gets significantly more grainy.
Mids - I can hear mids a little better when NC is on, but they don't sound any better. Only louder.
Treble - There is a large spike in the 2-3KHz region that equates to the loss of transparency and increase in grain. Not to mention a loss of clarity as well. I don't really know what exactly NoiseHush was trying to do here, but it didn't work out too well, that's for sure.
Soundstage - Still congested. I would say there is even less space than there is when NC is off.
Overall - Perhaps the NoiseHush i7 would be good for general consumer use. It's obviously not aimed at audiophiles. For travelers looking for good NC and don't want to spend more for Bose's QC15 (which isn't too much better anyways, excluding the extent of the NC), the NoiseHush i7 would probably be a good choice.
For a general use headphone, I would advise to stay away from NC in general.
