“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.”

“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 and eased some of the discomfort I often find with on-ear (as opposed to around-ear) designs.”
