Amazon.com Product Description

Experience the world's first headphones that uses digital technology to realize incredible noise reduction along with pristine quality audio with Sony's MDR-NC500D. Reducing up to 99% of ambient noise from airplanes, trains, or at the office, the MDR-NC500D headphones have ground breaking new digital signal processing technology suitable for an optimal listening environment. Enjoy features that include three distinct noise canceling modes, artifical intelligence function that automatically selects the optimal mode, a digital equalizer that ensures high-grade audio without sacrificing the noise canceling effectiveness, and a lightweight design that offers premium comfort.

Noise Canceling Technology

Enjoy music in a quieter environment with MDR-NC500D's noise canceling technology that reduces ambient noise to enhance your audio entertainment. The headphones have an inside microphone on each earpiece that work with an electronic circuitry to create an opposite sound wave to reduce wave. It reduces up to 99% ambient noise when the noise canceling circuit is switched on. Perfect for loud and noisy environments such as planes, trains, buses, work or dorms.

Synthesizing with a sound in the opposite phase for ambient sound reduction

Digital Equalizer

Experience high-quality music reproduction and ideal frequencey response with the MDR-NC500D. It delivers a high S/N ratio that is achieved through digital signal processing.

Artificial Intelligence (AI)

Experience noise canceling optimization with Artificial Intelligence. Because not all ambient noise is the same, the Artificial Intelligence technology will automatically select the optimal noise canceling mode based on intelligent analysis of environmental ambient noise.

5.0 out of 5 stars Great for flights, August 4, 2008

Forgot to bring my noise canceling headphones on a recent trip and decided to pick up a pair of those on the return leg.

The built quality is very good, it comes with a nice (but quite large) case and a full set of cables and adapters.

Although I'm skeptical about the claimed 99% reduction in noise levels I must admit that the noise canceling is very efficient, it's far better than that of any other headset I've tried.

They're comfortable to wear for extended periods of time and the internal battery easily lasts for a full flight. A nice touch is that it also works with AA batteries should you forget to charge the internal battery.

My only complaint is the size of the case, it's much to big. Other than that those headphones are great and I'd recommend them to anyone with a bit of extra space in their carry on.

5.0 out of 5 stars Best noise reduction I've seen, October 11, 2008

This review is from: Sony MDR-NC500D Digital Noise Canceling Headphone (Black) (Electronics)

I bought these headphones after trying them out at Narita airport in Tokyo earlier this year. I didn't have time to charge the internal battery before the flight, so I used AA batteries in the included adapter cable. That was the only time that I used the external battery. I've logged about 75,000 air miles using these headphones without a single problem.

The noise reduction is excellent, and the headphones are quite comfortable. The digital technology allows the user to adapt the noise reduction curve to the ambient conditions.

Yesterday I swapped headphones with a friend while riding in the back of a Canadair regional jet between San Francisco and Albuquerque. Those of you who have ridden in that section of this aircraft know that it's one of the noisiest rides around. I found that I could barely hear my iPod with his noise-canceling phones, while listening was easy and enjoyable with the Sony digitals.

Since they're digital, the phones are thicker than other brands. That's not a big problem for me. However, the huge case is a problem and doesn't fit easily in my briefcase, so I've started carrying the headphones in a stuff sack with another sack for the charger and other accessories. Everything now fits fine in my briefcase and carry-on.

3.0 out of 5 stars Great Noice Canellation but Constant THUMPING!, March 27, 2010

Hello
I am an electrical engineer who travels extensively. I have used the Bose QC1 and QC3 for years and deeply appreciate noise cancelling headphones for flights (for the life of me, I cannot figure out why everyone isn't wearing them!).

On a recent trip, I lost one of the ear pads on my QC3, so I figured it was a good time to replace them with the new Sony digital Noise Cancelling headphones. I understand the technology well and expected a great product.

First, some complain about discomfort of these headphones. They are not heavy and I didn't find uncomfortable in the least. If my choice is wearing headphones versus listening to the drone of a A340, give me the headphones ANY DAY!

Now the good part: the noise cancelling is superior to anything that I have ever heard (though I suspect good earbuds, like Shure, are probably better. I am not a fan of ear buds). These Sonys are certainly better than the Bose. The sound quality is Sony-perfect and I could barely hear aircraft engines. Besides superior noise cancelling, the Sony blocked out ALL noise, including talking or those damn crying babies, whereas the Bose only cancelled out the engines, with little attenuation of baby noise. DSP to the rescue-Sony has done a superb job of noise cancellation!

And, now for the bad part: These headphones have a VERY annoying thumping problem that comes and goes. It sounds as if someone is constantly thumping on the headphones on a windown and it can be loud. The problem seems worse on aircraft but I am sitting in the basement right now and I can still get the thumping. There is a definite problem with the noise cancelling algorithm that causes the phones to start thumping at a low frequency. On a recent LAX-ORD flight, I found that the thumping noise could be influenced by pressing on the phones or even leaning back in the chair. Sometimes even the slightest pressure on the outside of the cans causes them to start thumping. To stop the thumping, you lift one of the ear cups momentarily.

I found that sometimes I could move my jaw around and start or stop the thumping. I think the thumping is also somewhat dependent on ambient noise. Right now I am in the basement and the only noise (absolutely, totally cancelled) is the furnace. The thumping is pretty much gone until I touch the cans. I might be mistaken, but it seems to me that the thumping starts whenever the actual speaker elements get close to my ears--leaving little air space under the cans. Maybe there is a problem with a microphone pick-up inside the cans?

Nonetheless, on the most recent flight, the thumping became so persistent and annoying that I simply took them off and put them away. I was disgusted! There is a design problem with these headphones and Sony needs to figure out how to fix their DSP algorithm. And I need to figure out how to unload these phones. Because, while they are, by far, the best noise cancelling headphones I've ever heard, the obnoxious thumping makes them useless!

For now, I am going back to my Bose QCs until Sony get's their DSP act together.
