Le système anti-bruit actif est très sympatique et fonctionne réellement. Bien sûr dire que 99% des sons sont bloqués c'est un peu n'importe quoi, mais le résultat est intéressant. Ils sont très confortables et la qualité sonore est très bonne.

I'm rating this headphones only with two eggs because of the cons I mentioned, the notorious weakness in both the headband and the clips of the carrying case, and because I can't believe they broke after 4 months, but I can't deny that the audio quality has no comparatives, the music comes to life...

Highest quality audio possible; music is superb when listening with this ones; internal amp; noise cancelling; rechargeable battery; external battery compartment in case you run out of charge from the internal one; mini jack connector and adaptor; hard carrying case

The headband is really weak and flimsy; it broke after 4 months or so under normal use; I'm very obsessive taking care of my gadgets; not to say taking care of a 450 dlls headphones; and Sony said they could not be replaced because they are considered an "accessory"; and I thought: "a 450 dlls...

I received these as a gift for Christmas. Put the battery in and they don't sound any different between on and off. Actually there is slightly more noise when they are powered on. Went outside where there was more ambient noise and there was no difference between on and off.

Nothing

It doesn't seem to do anything

I replaced a pair of Bose with these as I wanted to try something new ... for my needs big mistake, the sound is great but if you want portability ( I am on planes a lot) then the carry case is a lot more bulky and having a charger (for me) is not as convenient as using a normal AA battery.

Sony boasts that its Sony MDR-NC500D headphones are the first to use digital noise-canceling technology. While a built-in digital equalizer is a step in the right direction, these headphones don't do much more than many of the other analog noise-canceling headsets we reviewed.

Digital technology shows the future of noise cancellation technology

They have no passive play option

The Sony MDR-NC500D Digital Noise Canceling Headphones cost $400. While that might seem like a lot of money, I can only suggest to you that these headphones are akin to sliding a stick of warm, melty butter into each ear - not in the sense that sticking butter in your ears would likely impede your...

Sony is making a lot of noise about its latest noise-cancelling headphones. The usual way this type of headphone works is that the device "listens" to the ambient noise and broadcasts a "mirror image" of the sounds into the wearer's ears, thus neutralising background noises.

You will be glad these headphones have a "Monitor" button so you are able to listen to what people say to you. Otherwise you'll hardly hear them. Even switching them on in an apparently quiet office environment gives astonishing results.

The Sony headphones have a battery life of sixteen hours - enough for all but the longest long-haul flights - and if you supplement the integrated rechargeable batteries with a pair of AAs you can well get 28 hours out of them.

The Sony MDR-NC500D headphones are smaller than the average over-ear, decked out in faux-leather padding, and made of a glossy black plastic. As over-ears these headphones aren't exactly inconspicuous, but at least they look sharp.
