Great Quality but Can Improve
These headphones do exemplify a qualioty product. they are constructed well, package and travel extremely efficiently, are true to their charge specifications, and are a good buy. They are generally comfortable, but for a long flight (i,e, more than 2+ hours) still require you to shift them to avoid discomfort on the ears. The sound quality, both with and without the noise canceling turned on, is crystal clear and superior quality; although can be slightly light on bass in passive mode. The one item most concerning is that while they are exceptional at filtering out the airplane engine sounds, they are fairly ineffective at filtering out other ambient noises, such as passenger voices, the clinks and clanks that occur on airplanes, the annoying announcements, or the coughs and sneezes. Still, they do muffle enough to provide a good, restful environment allowing sleep or peaceful reading. Overall, a worthy investment.
Pros: Compactness, sound quality, tangle-free cords, built in rechargeable battery (no fumbling with AA's).
Cons: Noise canceling above average but not great, and not much else.
