NC is rated out of 5 by 29.
Rated 5 out of 5 by dannyman from Amazing Sound and Battery Life, But a Bit Heavy I bought these a couple months back, and they sound amazing! The noise cancelling works extremely well, and the battery lasts an almost unbelievable amount of time. I've only charged it about 3 times since when I got it 6 months ago. It does work without battery, but it cuts out the bass, when noise cancelling is on, it brings it right back though. They are surprisingly comfortable considering the shape, but they are quite heavy. After an hour or two of use my ears start to hurt, which is a shame because the sound from these is truly amazing. I just wish they came with more wire options such as Audio Technica, but that isn't such a big deal. Pros - Amazing sound, comfortable if not worn for long, extremely long battery life, unique design Cons - Quite heavy, only one cable apart from charging

Rated 5 out of 5 by ajr017 from Great sound, build quality, and features! I've only had a few weeks to try these out but so far I'm extremely impressed. The sound quality blows away Beats, Sol Republic, or Bose headphones I've used in the past. So often nowadays headphone manufacturers love to throw in ridiculous amounts of bass without taking into account that listeners may want more than a reproduction of an 8" subwoofer blowing out their eardrums. The Harman/Kardon NC headphones do a wonderful job at keeping the bass tight and boomy, but not sacrificing the minute details of each track. It's truly a joy to listen to these and experience sounds I've never heard before in my music. The noise canceling is great too; haven't used them on a plane yet but vacuuming and other loud household noises are severely suppressed. My only "complaint" is that the sound quality without the noise cancelling feature engaged is not the same, as you lose a little bass/mid-range quality. Honestly though, with a rechargeable battery and not having to worry about replacing AAs, you can safely always listen with the NC feature engaged without a care in the world. I shouldn't even be complaining though as being able to listen to these without NC active is a big bonus and further sets these apart from other headphones. Build quality is excellent as usual, and I actually like the heavy feel (like a door on a fine German automobile!). All in all I'd highly recommend these even if you don't plan on needing them for a plane ride, etc. Simply engaging the noise cancelling feature while lounging at home will give you an experience you'll rarely get with another pair of headphones. Oh yeah, and the NC "static noise" that others might complain about is virtually undetectable while the NC is active. Wouldn't have expected anything less than awesome from Harman/Kardon!

Rated 5 out of 5 by Charles from Nice Headphone I bought this two weeks ago, and the shipping was very quickly. It makes me feel like real, such as go to the concert. Nice sound, especially alto voice.

Rated 5 out of 5 by Weiße Raute from Buy it without second thoughts!!!! The best Noise Cancellation headphones I have ever tried. Music quality is so pure and pleasant to hear unlike other over-rated brands. Best thing I love about the headphones is that it can work without NC when it runs out of battery. Lot better when compared to QC15 and other so called top models. One disadvanage is that the connecting cable has a jack on one side which is not universal. Other than that no complaints...
