This is excellent at Noise Cancellation.
Duo Accompli
Any way, these are a great alternative to the Bose headphones, frankly dollar to performance these are probably a MUCH better deal.
Problem is the plastic is cheap and breaks less then a year out.

The Denon AH-NC732K is a very nice pair of headphones. They are compact, comfortable, and sound very good. The noise canceling works very well taking care of engine noise and other low frequencies. The included carrying case is perfect to slip in your briefcase or carry on bag and it has enough room for all of your adapters and cables.

The headphones don't fit around the ears like the larger Bose QuietComforts. They rest on and cover the entire ear. I was surprised that they were comfortable to wear. It took a little fiddling around to get a secure fit but it was worth it. The headphones feel like they are creating a seal to achieve maximum noise reduction. In fact if you just put them on without creating this "seal" you might not think much of these headphones so proper fit is key.

My first test was for noise cancellation. A lot of people will use these just for that feature and not even play any music through them. I ran an airplane noise WAV file through my desktop stereo system to simulate being in a plane. After cranking up the volume on my JBL 2.1 system I put the headphones on. There is a small switch on the side on the headphones to turn noise canceling on and off. With it off you could clearly hear the humming of the engines, the beeps of the seat belt indicators, and the general noises of cramming a hundred people in a cabin. Turning the noise cancellation on reduced these noises by 80%. The engines were barely audible and the beeps sounded like they were further away. Overall I was pretty pleased with the noise cancellation. Hopefully they work as well on a real flight.

I tested these for music with an iPod Nano and my stereo system.

I bought the Denon AH-NC732 headphones after reading all of the reviews, but for a different application. I operate farm machinery, and the Sony earbuds I have been using with my MP3 player were uncomfortable and prone to being dislodged easily.

The Denon headphones have proven to be an excellent replacement. After about 40 hours of use, they are doing exactly what I bought them for. They very effectively reduce the engine (diesel) noise, provide very good sound, and wear comfortably for long periods of time in the field. They appear to be well-constructed, and if handled sensibly they should hold up to the use I purchased them for.

Along with some of the other reviewers, I doubt the claim of "99% noise reduction" and agree that about 80% is a more believable figure. I like the fact that I can hear my music well, and still audibly monitor the equipment I'm operating. For me, this is the perfect package.

I was very impressed with the price. I had looked at Bose headphones in an electronics store, and for about half the price, I think the Denon's are a great value.

I'll update this review if any issues arise, but for now the Denon's are doing very well.


UPDATE! After two weeks of use, the right-side earphone began emitting loud static while in noise-canceling mode. I changed batteries and tried two different sources with no effect. I contacted Denon's factory repair site and got the OK to return them. The headphones came with a one-year warranty.

I returned the Denon's in the box I received them from Amazon, along with my proof of purchase dated two weeks earlier.

If you don't want to read my boring review, skip to the bottom where I praise and recommend these.

First, let me thank the previous reviewers. I was contemplating these for several weeks based upon the other reviews.

The other reviews are spot on in their assessments. They do take a few minutes to adjust but then are quite comfortable. I don't wear them hours on end, so I cant speak to the comfort level of prolonged use, but I don't have any complaints about the comfort and fit using them on and off throughout the day when I want some isolation.

Another reviewer referred to the excellent sound quality. I do indeed hear my music with more clarity and richness. I can hear details with these that I have not heard with any other earphones. I notice this mostly in the mids and highs. I should note most of my music is recorded at 192kbs and 44 KHz.

I had used the Sony MDR-NC40 headphones but wanted something a little better. I bought the Denons about a week ago and have been very impressed with the sound quality and noise reduction. I work in a computer room with constant background noise. Putting the earphones on immediately drown out some noise, but the NR is impressive. You dont have to even listen to audio to dampen the outside noise. Oftentimes I use them with NR only and it definitely makes a noticeable difference.
My wife has the Bose Quiet Comfort. They also sound good, but not "$250 good".

For the value, I was surprised at the price point. I bought these through Amazon for almost half as much as other products.

I consider myself a sound enthusiast, because being an audiophile is way too expensive for my taste. These headphones have surpassed my expectations although the previous reviews set my expectations fairly high.

Summary of my thesis on the Denon AH-NC732:
In my opinion, better overall sound than Bo$e for less money. They did not disappoint.
