Summary: This is my first pair of noise canceling headphones so I don't have much to compare them to.
What I do know is that I wore these for two 14-hour flights on a C-17 cargo plane, and two 2-hour flights on a C-130 cargo plane.
Summary: These headphones are very nice. We used them on a recent flight and the noise cancelling worked well. The comfort is not as good as my husband's Bose headphones, but with the price we paid on Amazon we feel like we got a great value.
Summary: These headphones were a great choice! From my perspective, all positives and no negatives. I almost purchased the Bose headphones at more than three times the price I paid for the Panasonic product but I'm sure glad I didn't!
