These headphones may be the some of the most expensive on the market. However, they are NOT overpriced! They do exactly as they claim, the block outside noise while delivering high quality sound to your ears. Why then do they not get full marks? As far as comfort goes, I've never worn more comfy headphones. However, when their battery gets low, if you don't change it immediatly, it will go on and off, creating a kind of thump each time they turn off, and it's a tad uncomfortable for the ears when in such an isolated sound environment. That's the only negative thing I have to say!
I wear these on planes, at work, even at home to drown out whatever noise my family or boyfriend were making, and they work wonderfully. They also feature a carrying case that contains a protected environment for travel for the headphones, as well as several different attachments including a headphone extention cord, for increased movement, and an attachment that fits into most plane headphone outlets, so you can watch inflight movies for free!
