The noise cancelling works pretty darn

I have not had a chance to test this function other than around the house, hard to motice a big difference, maybe they will work better with louder noises.

The noise canceling works well enough for me: when using my snowblower, as well as in more normal environments

I also have the Sony MDR-ZX780DC from Costco which I got on the very cheap during a sale and while those do not have usable noise cancelation, the sound quality and comfort are better than the Sennheiser 4.50 and for only a fraction of the cost.

These headphones have amazing noise canciling abilities and the sound is amazing.

If you have "white noise" at work, this is a Godsend because it will almost eliminate that humming noise of a/c and fans etc

They stay connected and reconnect easily to my computer, their noise cancellation works very well with no hissing noise, and the sound is Sennheiser great

Great active noise canceling headphones.

Overall they sound great and fit comfortable with good noise cancellation and I am happy with the purchase.

Didn't suit my need - to block out voices & and spurious noises when working

Good noise cancelling

Noise cancelling works well, not perfect but works really

Noise cancelling works great.

Also the noise canceling does not work without sound input

Great sound, comfortable, great battery life and really good noise cancelling.

the Noise Cancelling Feature works differently while you are on a Phone Call (it amplifyes and repeats some outer noises inside the

but it makes the loud noises more bearable.

: 6/10Bose still has the best proprietary noise cancelling technology on the market, and these Sennheiser's don't match up to Bose's noise cancelling

Good Sound, Amazing noise cancling for the price, Extemely clear, great battery life, good wireless connectionCons

The sound quality is top notch, the noise cancelling feature works great, and they are comfortable even for hours on a long flight.

Pros: I like the feature where you can enable or disable noise cancellation

Very comfortable, easy to pair, and excellent noise supression.

Noise cancelling works well, not perfect but works really

excellent headphones with good noise reduction

So for guys like me, I wish there was a more aggressive noise cancellation

Best noise cancellation that I've had in a pair of headphones

Noise canceling only works when the cable is connected from my experience.

Maybe a three level adjustable noise cancellation with the final level set aggressively

Good noise cancelling, quick charging, great sound.

What you pay here is for the slightly above mediocre noise cancellation which is purely from the ear cushion's seal afterwards the ANC/noise guard just takes out some minor droning and lower frequencies it was never meant to block conversations or loud music or anything of the

Great sound quality, 5/5 if bass was better, noise cancellation not bad, but not great.

Cheap headphones they always make sharp noises when I'm

Great noise canceling.

Nice active noise reduction...but ear cups are too small and uncomfortable.

They do pass through exterior noises well during calls though, so I could hear the person to the right of me crystal clear from 20 feet away when I had no music on

The noise cancelling is decent - not as good as the noise cancelling on the Bose models I've tried - but good for the money.

These are great noise cancelling headphones at a reasonable price

It seemed like they did a decent job killing general ambient noise, but I don't really have anything to compare them against as a reference for "WOW these are amazing" levels of ANC

I would like - a better noise cancelling off/on

The noise cancelling works, but it just mattes out stuff, and doesn’t really mute the low end frequencies all the way

Great sound and strong noise cancelling

I read several online reviews about the top noise cancellation headphones and these HD 4.50BTNC's were always included as the value product that were "almost as good as the Bose QC-35's

They're reduced to more tolerable level, and moderate music further obscures the noise without making me feel exhausted at the end of the day like I was.

They block out ambient noise very well, even with the NoiseGard function turned off

Pretty good noise cancellation

Cons:- Microphone picks up even the quietest background noise and amplifies it like a hearing aid or spy

good+ Noise isolation is good (without turning NC ON)+ Sound is good even in

Cordless, with better noise cancelling, and far superior sound quality.

she tried to hit a Wooden Spoon on the counter in a constant pattern every about 1 seconds, and it took good 2-3 seconds for the Banging to Disappear, but it cleared it... as she changed the pattern, every time it took about 2-3 seconds to re-clear the noise, but once gone, i could hear her perfectly

These headphones are high grade and have amazing noise cancellation, the sound is great along with soft comfort when wearing them for over and hour

If you're looking for good quality noise-cancelling headphones and don't want to pay $350-400, this is your best bet.
