Noise canceling technology:

Noise canceling headphones reduce ambient noise and provide a quieter environment to enhance audio entertainment.

Ambient sound is reduced by synthesizing with a sound in opposite phase produced by the noise canceling circuit.

I've had this product for 3-6 months

Great sound - not sure about design...

Pros: Great sound / Pretty tough...

Cons: The ON/OFF Switch // Fits a little tight for some // The cord is a little short...

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.

MDR-NC40 Good Product

Pros: Light weight, easy to wear for full flight time

Cons: No complaints

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

Pros: You definitely notice the great amount of reduction in ambient noise.

Cons: The N.C.Headphones on & off switch and the monitor button, the product is made for N.C. so why have a switch?

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.

Best Headphones I've had

Pros: Great Sound, very comfortable, not too expensive.

Cons: the switch that hangs from the cord is bothersome.

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!
