Review title: More ear-piercing feedback
Product review: I bought these to reduce in-flight noise when I fly. I did a side-by-side comparison in a store with my wife's Bose headphones. I couldn't hear much of a difference. They sounded great in the store.They were useless on the plane.Like many others, I heard ear-piercing feedback when I turned the headphones on and tried to listen to the in-flight movie audio. I tried adjusting the fit and the volume. At best, there was still a faint bit of feedback. Even without the movie audio -- with just the noise cancellation on -- the headphones gave me a headache. I switched to my wife's Bose set for a while and had no trouble at all -- no headache and no feedback.
