How much sound can these headphones cancel out?

Hi Tony. My first pair were pretty good. Most constant background noise was filtered out (traffic noise, engine noise in aircraft etc.). I could still hear people speaking although at a lower volume. When friends tried them, they were all quite impressed by the noise cancelling.My second pair weren't as good as the first pair. That said, if you open the ear pieces (they are held together with small screws) you will see a small potentiometer (one in each ear piece) with an adjusting slot.I fiddled with this and noticed it increased/decreased the noise cancelling. If you turn it too far to increase noise cancelling, movement of the headphones causes a clicking sound. Hi Tony. My first pair were pretty good.

They can't make any situation sound like an empty concert hall, but they really take the edge off. I expected mine to make airplane rides be silent, but they don't do that. They really cut down the loud humming (on planes) and make it much easier to sleep on planes. They were worth the money for me for the much to reasonably quiet plane rides.

They don't cancel everything, but they are amazing. I love them on a plane with my iPod no crying baby ever bug me. They pretty much get the whole plane noise just by themselves.

I've heard it ranges from 15Hz to 28kHz. I would recommend a headphone amplifier if you want to enhance the lows. They are definitely comfortable and provide pretty good passive sound cancellation.

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.

They do not do much noise canceling. I would prefer an AKG headphone. They are very faithful to the music. They need a good amp or good headphone section, though.

They do not seem to be noise canceling. However, they do a decent job at it for non-noise canceling headphones.

I'm in the same boat. I'm reviewing headphone sets primarily based on their noise cancellation abilities -- I don't even need audio. Recommendations would be welcome.

They aren't noise-canceling headphones, as in they don't have "Active Noise Control" (http://en.wikipedia.org/wiki/Active_noise_control) but when I put them on, things definitely get much more muted.

They are only noise cancelling as much as anything else that plugs up your ear. There isn't much external noise when playing music, however. Overall they were decent ear-buds for the money; just make sure they are the full item, rather than the OEM variety, as those only come with one set of silicone inserts and may not fit all ear types!

3.5mm is a standard audio port. They're kinda over ear, but not very noise canceling

They isolate very well. You're not going to have to turn the volume up much at all. Usually, maxing these headphones on a phone or iPod isn't going to be too loud, but the isolation usually makes it loud enough. I'd suggest getting a good DAP or a powerful phone anyways. I think your biggest concern should be how hot your ears will be :D

You can use them with noise cancelling turned off. Just like a normal headset.

85 db compares to busy street noise, or a vacuum cleaner. These headphones in NO WAY come close to being able to block that level of noise with it's so called noise cancellation effect. It can only mask outside noise of that intensity by making it's own noise, that is, by serving in a headphone capacity and playing music or other such input. Noise "cancellation" is a grossly misleading appelation when applied to these headphones. They DON'T block noise to any appreciable extent--not like ear plugs or shooter's headphones do/would... which is what I suggest you need if you're looking to protect your ears, not blow more noise into them.

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!

I disagree with other comments here. I don't have my music quiet, per se, but yes, others next to me can hear sound from my headphones. They do completely surround the ear, but that is not the same as sound-cancelling.

I don't know, I tried them at home while trying to study for a major exam, and they weren't that good at noise cancellation at all. I'm getting ready for an international flight n I'm looking to get some Bose instead for my flight. Good luck!

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/

No, they aren't, if im listening to music at a moderate level and my clustermates are talking, i can faintly hear their voices. Although, if you turn up the volume, it should cancel them. But to answer your question straight out, no they are NOT noise canceling.
