    Bought these headphones 1 week ago and I must say they exceeded my expectations. The sound is amazing. Most stereo headphones sound too gushy, that is the sound comes at you all at once, you don't get the separation of bass, treble, and the higher notes, but with these you get the full spectrum of sound. These are not quite as good as the Bose headphones, but run a close second. Sony put alot of quality into these headsets, you can use them for a variety of occasions, including sports workouts, plus their foldable design makes them ideal to carry around almost anywhere. They're great!

    Don't Buy Them

    By steelcar

    from Houston, TX

    Comments about Sony MDR-NC40 Stereo Headphone:

    I understand that these headphones may seem relatively cheap in comparison with other on-ear noise canceling headphones but the the cheap build quality override this plus. Honestly, it shouldn't be called a noise canceling headphone because it doesn't to squat. For this price you are better of with in-ear headphones.

    Great buy at Weekly Special price

    By TJSH

    from Middleburg,Va

    Comments about Sony MDR-NC40 Stereo Headphone:

    Very good noise cancelling. Sound in noise cancelling mode is very good, but probably a little too much bass for some tastes, Sound with noise cancelling off is still quite acceptable so if battery were to die still can enjoy music.

      Best Uses

        Comments about Sony MDR-NC40 Stereo Headphone:

        They cost about $15 over what I wanted to pay, but I still purchased and they are really great. I use them mostly when flying and they perform very well. The headphones fit very well in the case, which has a spot for an extra battery (very handy). The on/off switch is located on the cord with a monitor button if you need to turn it off for a few seconds. This has a helpful clip to attach to clothing. My only con is that when I wear for more than 4 to 5 hours, such as on long flights, the begin to make my ears hurt. However I do not think this would be a problem for most customers. Once I even slept through takeoff, without even turning on the headphones.

        Great Headphones

        By Anonymous

        from Princeton, NJ

        Comments about Sony MDR-NC40 Stereo Headphone:

        These headphones do work without being on (without a battery), but the sound quality is not so great. When you turn these headphones on, they become super high quality. The sound quality is really amazing. I highly suggest picking up some rechargable AAA batteries from radioshack to go along with these. Great job Sony!

        Excellent.

        By Anonymous

        from New Hampshire

        Comments about Sony MDR-NC40 Stereo Headphone:

        I've had these headphones for about a year and a half now. I was amazed when I compared them to the Bose equivalent. I honestly thought for the price, Bose should have been embarrassed. These headphones perform so well! As soon as you flick the switch, the quality of the music goes WAY up. These headphones cancel out noise so efficiently, too. You can actually hear your music when you use them on airplanes, it's really great. I am a huge fan of these headphones, and I always recommend them to friends.

        Great sound - not sure about design...

        By FiveQs

        from Topeka, KS

        Comments about Sony MDR-NC40 Stereo Headphone:

        If you "use" these headsets your going to burn through a lot of batteries. Don't even think of letting your kids use them. Why SONY would design this product without an auto shut off feature is a crime. If your not using the headsets powered ON they sound very poor indeed. But powered ON they are great!!! Dear SONY, DITCH the SWITCH and auto sense when your plugged in. It would be a much better product if it was wireless.

        Cheap construction, uncomfortable

        By nyanko

        from Davis, CA

        Comments about Sony MDR-NC40 Stereo Headphone:

        Earpiece fell off of headpiece after 7 months of sparse use, no rough treatment or misuse. Appeared to be held on by a screw with an inaccessible head and a piece of cheap plastic superglued onto the headpiece. Reason for sparse use was that they made my ears hurt after an hour of use, and the sound quality was horrible if the noise canceling wasn't switched on (only wanted to use it when necessary to conserve battery power!).

        MDR-NC40 Good Product

        By marty

        from Hunstville, AL

        Comments about Sony MDR-NC40 Stereo Headphone:

        After reading the reviews for the MDR-NC40, I thought I'd give them a try. What a difference. Made flying relaxing. This pair is worth the price. Noticed three other people on my flight who owned them. They, too, were pleased.

        First N.C. Headphones Ever Purchased

        By Jvstn

        from Undisclosed

        Comments about Sony MDR-NC40 Stereo Headphone:

        I haven't owned any other noise canceling headphones before and I have got to say these are worth every penny. I don't think I can go back to using ear buds, after using these. I've always liked sony because I believe you can never really go wrong with any of there merchandise and I see them as a really reliable source for great quality electronics & technology. I look forward to purchasing another pair. I am very satisfied with this product. Thanx Sony.
