    In terms of audio quality, it is interesting the difference that the little AAA battery can have. When switched off, I'll admit the headphones sound a little underpowered and definitely do not pick up on low end sounds very well. However, with a flip of the noise-cancelling switch, the bass response is greatly enhanced (I assume that sony is also amplifying some of the frequencies as well as using noice-cancelling strategies here), and the sound is very full and rich. You can also hear the effectiveness of the noise-cancelling by leaving the cord unplugged and switching the power on and off. I never though I'd get such nice sound from such small headphones.

    Cons:
    Using them for about 2 years with ipod nano.
    Noise cancelling is not enough for me, tested at:
    plane - though they are cancelling alot of noise, good enough amount of noise still reaches ears;
    public transport (busses & subway) the same.
    Most bad about these headphones is their bad durability. Ear-phones are falling from screws holding them, one side broke where ear-phone connects with metal part of headband.
    + they are not suitable for use during rain/wet weather.
    Overal conclusion
    Good for listening music on the go during good weather and at home;
    Good sound quality (I like their bass with noise cancellation On)
    Not recommend for frequent travelling due to non-durability and not enough noise-cancelling and recommendation not to use in wet weather. Also my ipod nano produces not high enough sound for noisy enviroments like subway to overlap train sounds or our bus motors, required Headphone Amplifier when used in public transport (not planes).

    Comments about Sony MDR-NC40 Noise-Cancelling Dynamic Stereo Headphones:

    I purchased these for a long 13 hour flight, as noise cancelling are the best for reducing that annoying (ambient) plane sound. The headphones work great in reducing the engine noise and have good quality sound particularly on the plane, however, they are not without its own problem. The design of the headphones is such that it does not cover over your entire ear, rather the pillow construction of the phone presses upon your ear firmly and immediately blocks some of the outer noise even without the noise cancelling turned on, thats a good thing, but the pressure on your ear eventually caused pain to your ears after long term use. After about 6-8 hours of wearing them I had to take them off because my ears were in pain. On my long flight back a week later, my ears were still not used to the pressure and i had to take them off periodically because the pain on the ears was annoying.
    Overall, they are good headphones but not the most comfortable if your intention is to wear them for long periods of time without taking a break. Next time i will try headphones that fit over the entire ear instead of pressing on them.

      I use this only for flying. It cuts out the noise of the engine. They are compact and lightweight and come in a great little carrying case.
      Im sure that compared to a very expensive pair the sound is not comparable, but I am happy with these.

        I only use these for flying to black out thee noise. Its much less tiring. I didn't want to spend a fortune on them and the Bose were too big and bulky. these are sleek and i don't feel like they are squeezing my head, Well worth the money and they come in a nice carrying case.

          Those Sony Noise-cocelling headphones are very good for those who, like me, want quality at low price. I first used them on a train for 12 hours, and it really makes a difference. And they can be carried everywhere. I really recommend them to every music lover.

          Plan on using the product at home when I don't want to make too much noise. Purchased a 10' extension. Turning the power on Really makes a difference in the sound quality. Having the mute feature is very helpful. Little flimsy, but got on sale at a great price.

            Very good headphones

            By PKAudioZen

            from Australia

            Comments about Sony MDR-NC40 Noise-Cancelling Dynamic Stereo Headphones:

            As other reviewers have noted, these headphones sound very good when the noise cancelling is switched on. When switched off, they sound pretty bad. But I still give them 4.5 stars out of 5, because they sound so good with NC on, and are comfortable and compact. I will just leave the NC on whenever using them, no big deal.

            I'd love to know exactly why the sound improves so dramatically when turning on the NC. Other NC headphones don't have such a difference between NC on and off. Maybe its the price to pay for such great sound when its on. I own some AKG NC 480 headphones and the Sonys sound better, and are much cheaper than the AKGs.

            The monitor button is a nice touch - a switch for temporarily shutting off all sound and NC.

            Well done Sony!

                                The headphones live up to the reviews. They are compact enough yet sufficiently large to wear comfortably for extended periods of time. Noise canceling works fine.

                                  These babies rock! They are very comfortable and work well. The sound must be amplified with the noise-cancelling switch on given the marked improvement in the bass. Really pretty remarkable for earphones of this price. Thanks Sony and thanks B&H for carrying them available!

                                  Comments about Sony MDR-NC40 Noise-Cancelling Dynamic Stereo Headphones:

                                  for the price, it works as expected. It cancels out back ground noise such as ventilation fan or engine noise on a road trip. I have not had the chance to take it onto a light yet but based on the other usage, i am sure it will do the job.
                                  It's fairly comfortable to wear.
                                  I gave it 3 stars because
                                  1. sound quality - I am no expert, but the sound quality did not impress me. I was hoping for a little more I guess. It's not bad, just not exceptional
                                  2. durability - I have been very careful in using it, but I am always in fear of tugging the wires too hard breaking it. It didn't give me confidence that it was build to withstand a lot of usage on the go. So if you are only using it on trips while sitting down, it's perfectly fine. but if you want to use it walking around, i'd say it would not withstand that type of usage.

                                  Overall, it's a good value and works as I expected.

                                  I work in busy coffee shops sometimes actually doing sound editing, and the noise can be great. So I decided to try noise cancelling headphones. These are better than the on-ear non-cancelling headphones. The headphones are comfortable and they cover the ear well so there is some passive sound elimination as well. The lower droning noises are adequately cancelled, and things like voices are taken down a notch, not as significantly as I had hoped. These do help though. Also like the carrying case. The sound is not very good when they are not turned on. And the cord could be longer and the turn on module could be better placed.
