Not bad without sound on. But once you got music or something playing, they are pretty good.

They have noise isolation there is some difference between isolation and cancellation-see link-http://www.howtogeek.com/howto/44328/htg-explains-how-do-noise-reducing-headphones-work/

Noise cancellation is great, they plug into your ears. The sound quality is awesome!

These headphones are junk so I would not recommend them at all. Ours fell apart within months and the company is terrible to deal with. they are moderately noise cancelling..

No, they are not noise canceling. Frankly, I feel safer when I can hear a bit of the sound around me.

The ones I have are black passive noise isolation, and the plastic around the ear cups is a matte finish. I think the active noise canceling ones have the gloss finish.

I would think not. As others have said they are not noise cancellation. If you can deal with that one problem then you are set because they are overall fantastic headphones for the price range.

I am using them on my Galaxy S2 running Jelly Bean & have no problems hearing them with noise cancellation on. Did you try inserting new batteries. Also do you see a red light on your ear buds when noise cancellation is on? The buds plug into a standard headphone jack & have nothing to do with the phone OS. If you can hear other headphones on your phone fine, but not the NC20s, then just return them & ask for a replacement.

I have no idea, I haven't used it for that yet. I'm using for noise cancelling while listening to music or playing games on my computer, tuning out TV or other household noises. So far I like them.

If you mean are they noise cancelling the answer is no. And these headphones are uncomfortable when you wear them for a long duration.

No, but keep in mind that these aren't aren't active noise cancellation phones. They isolate by virtue of their in-ear design, but don't reduce noise nearly as much as active circuitry does

I would say about 90 percent of the outside noise is cancelled by the headphones but there is no difference when you turn on the noise canceling feature.

Yes it's noise canceling. The bass is very good and the drivers are incredible. Very good head set.

No, they are not noise cancelling. In fact, I've used mine on flights before. While they block the engine noise better than my earbuds, they are far from completely eliminating the engine noise.

They do not have a noise canceling system designed into them. They are however a great sounding set of headphones.

These are open end headphones and do not provide much noise cancellation. That's part of the reason their sound stage is so expansive. These headphones are best listened to in a quiet environment, but they sound oh, so fantastic!
