Review title: Seem durable, work well
Product review: Have had a set for about one month. After seven trips (5 jet, 2 turboprop) - engine noise is easily cut 50%. Noise reduction is biased toward lower frequencies, but makes sleeping MUCH easier. Since the noise reduction electronics are integrating, passenger comments, conversations, announcements, etc. are actually clearer (better S/N). When the aux. input jack is used for MP3 (Palm, Rio) results are superb. Also works very well on output from an IBM laptop. Although some reviewers had mechanical problems, I've had none, and must confess to thoroughly mashing the headphones into a small pack numerous times.
