PARADIGM H15NC ACTIVE NOISE CANCELLING HEADPHONES REVIEW
If you're looking for comfortable headphones with active noise-cancelling, I definitely suggest trying out these Paradigms ' especially if you're travelling by air as low-frequency noise such as engine noise should be well in the range of their noise-cancellation abilities. And the 40-hour battery life should last for most round trips.
PARADIGM H15NC NOISE-CANCELLING ON-EAR HEADPHONES
Comfort-wise, I felt the Paradigm H15NC's will appeal to most head sizes and ear shapes. I found the memory foam padding to be quite comfortable...if you have a $300 budget and want active noise cancellation, then the Paradigm H15NC simply rock.
