I see that these are not active noise cancelling, but how well do they passively isolate outside noises?

They are pretty good at isolating outside noise because they are a complete over the ear design, and unless you have dumbo ears, they should fit over your ears to seal out most ambient noise. The sound in the headphones is exceptionally loud too, and the bass is pretty deep and thumpy (if there is such a word). I like them because it still allows me to hear stuff going on around me if for example, cars horns, or someone calling my name, etc. I have not tried them on an airplane per se, so in terms of drowning out engine noise, i cannot say, but in a car, the road noise is non existent.

They don't CANCEL noise. That constitutes destructive interference, and requires a circuit to 'hear' the sound and duplicate it in reverse to 'cancel out' the sound. These ISOLATE. Quite well.

They are very good for drowning out ambient noise, hums, rumbles, buzzes, etc. They are not really supposed to drown out irregular noises, like speech or loud music. I find they do make what I am listening to stand out from the back more sharply, and deaden pretty nearly all external sounds somewhat.They are also well padded, which keeps other sounds out even when you don't have the headphones switched on.

From my experience, these would be about same effectiveness of any passive closed headphones. The noise cancellation is not very effective. I fly frequently with Bose Quietcomfort series headphones which are the best for planes.

Volume control? If you are asking if these are electronic noise reduction/sound canceling earmuffs, the answer is no. These are passive, tradition hearing protection - dampening all sound, as long as you wear them. They are rated 26dB, which is excellent for outdoor shooting of all types. If wearing at an indoor range I like to wear these over an in ear device (foam plugs or surefire's), especially when going from pistol to rifle.

Glad to help...People often see to be able to tell when I am using the headphones....when in low to med noise environments the output is great. Seemingly the headphones do not defeat exterior noise so the result is often a mixture of everything that is going on my side of the call. Functionality is awesome...as long as you're in an enviro that is not noisy you will love 'em.

Not actually noise canceling but seem well insulated without much ambient noise bleed-in. Unless someone is talking loudly next to you and you are listening to something quieter (like dialog in a movie) they seem to work great for me.

These headphones don't have active noise canceling; however they do have noise isolation, or "passive" noise canceling. It's like when you cup your hands over your ears. They're actually not that bad at it either. I've had to use the MDR10R for in-ear monitors on stage before and I couldn't intelligibly hear anything that wasn't coming from them.

They'll block out a lot of noise, however if you're in an abnormally loud vehicle or other situation where there's a consistent droning noise you may want to look for active noise canceling headphones. If the sound you're trying to filter out is not loud and consistent active noise canceling will be useless. These headphones do _not_ feature active noise canceling but are closed back and will block out a lot of sound, such as people talking, TV in the room etc.

When music is playing at reasonable volume, they're pretty good at blocking background noise, but not perfect. If you're just wearing them over your ears without input, the noise cancellation is more of a soft noise muffling than anything else. I wouldn't call them "noise-cancelling" so much as "reduces extraneous background noise so you can focus on what's playing".

I wouldn't say these suppress exterior noise by much. I bought these because we have 3 people in our house that work evenings, and my wife can listen to the TV without disturbing anyone. She says she can hear the dishwasher a very small amount while wearing them. Just testing them myself some has to really direct their voice to you to be disruptive. A side note.....We LOVE these! The serve a great purpose and work fantastically!

They isolate sound pretty well, and pretty soon I will be getting replacement ear pads from beyerdynamic, which are said to feel better, and provide a bit better sound isolation. I will let you know more when I get them.

They work well. Key word is "isolate." I could still hear outside noises; they simply did not interfere with (or dampen the quality of) whatever I was playing in my ears. (...as mentioned by others.) Love the price. Will purchase a couple more sets.

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

Well, they aren't battery activated, they're passive. But once on, they do a great job of diminishing all ambient noises surrounding- give or take a few screams, or weights dropping or clanging around you. However, if you have your music going, all excess noise is a distant memory. After putting them to work in this morning's session, I cannot tell you how pleased I am with this headset!...

Yes. It's true they aren't noise canceling, but they do a pretty good job as far as I can tell. My parents complain that I can't hear them calling if I have them on, so that gives you some idea :-)

They are the most noise blocking head phones I've ever owned. That's not to say they're 100% noise proof. But you'll really have to try and hear outside noises.
