these headphones are good and loud if your one of those people who loves loud music then i recommend

-brand; good sound quality; stylish

-too expensive -dont cancel much noise -too big

The Sony MDR-NC500D Digital Noise Cancelling Headphones and one of the best set of noise cancelling headphone I have experienced. They block out slightly less background noise compared to the latest Bose models, but the sound quality and bass response are much better.

Comfortable; Good Bass

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.

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.

I'd wait a bit, they can't be this expensive forever,

Great quality sound; stunning noise cancellation; good design

Far too pricey

These 'phones are incredible. I paid far more than the 179 that Play are selling these for and at that price you are getting Bose/Denon beating headphones. The noise cancelling element has made some recent longhaul flights very easy.

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 actually listen to ambient music to help me sleep so I wear the headphones at night while sleeping..

Comfortable; Durable; Good Value; Great Sound; Lightweight

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.

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...
