Title: Must hear it to believe it
Review: I was some what skeptical about the effectiveness of noise cancelling headphones, until I turned these on in the airplane. The noise cancelling system alone, without music seemed to silence the roar of the engines by at least 20 db. Turn on the music and ahhhh! Sound quality: Hi-Fi. Traveling convenience: Excellent. Fit: A bit to tight on the ears, but comfortable enough for an hour or two.
