I read the reviews and saw some bad ones but decided to buy anyway for the plane ride from east coast to west coast. These sounded really good and canceled noise out okay.... as long as the cord was completely still, not touching anything. The sound from the cord is RIDICULOUS. I couldn't even listen to these. I pulled out my Apple headphones(and we all know how bad those are). Don't waste your money on these. ALSO the noise cancellation is basically just the headphones blocking your ear canal. If I hummed or sang along to the music there was a super loud echo in my head and I could hear every breath I was taking(similiar to the sound when plugging your ears). I hate these.
