Summary: For the money these give a good mix of sound quality and comfort together with the ability to fold up and be compact. The noise cancelling works well and to better the overall sound I guess you would have to spend much, much more. Certainly good enhough to be a very useful addition to music from the laptop / ipod while away. They come with a useful airplane adaptor - but be careful this can easily fall out of its holder in the case.
Summary: I recently bought a set of the Sony MDR-NC40 headphones as I travel quite a lot in my work and until now I have been using "normal" in-ear Sennheiser headphones, which are fine for standard use but I thought I would like to try a set of noise reduction headphones - just to see what they were like. I did not want to spend a lot (in case I did not like them), but wanted a decent set in order to give the NR a fair chance.
Summary: The headphones arrived within 48hours and were well packaged. The headphones are in a very nice case ideal for also holding my Sony walkman. The sound quality is excellent and they had a facility to attach them to your clothing so that the wires do not hang down. My only critisism is that I am a very small lady and I have had to pad the top because the ear pads are quite low. Not a problem to any normal sized person. Pleased I bought the product.
Summary: I bought these to use on a long haul flight as I was fed up of not being able to hear the movies on planes with all the background noise. The noise cancelling has obviously been tuned for aircraft noise as it worked well and the inflight movies were very clear, in fact I had to turn the volume down. The phones fold up quite neatly making them more portable and the case they come in is quite robust, the adaptor for the plane socket comes with the phones which is good.
Summary: I would say reduced the most irritating noise on my flight. Probably resulting in about a 30 to 40% reduction in the overall noise and made it much more comfortable to watch the in-flight movies. Very good for the money and comes with an in-flight adapter so don't buy one seperately as I did.
Summary: This is a great value product, much more comfy that any other headphones I've ever had and great sound quality. A few reasons I didn't give 5 stars. The noise cancellation is not top of the range, and only makes a minor difference. It does kick up the bass and lasts for hours on one battery, so it's not all bad. It is also difficult to position the hard head band comfortably on my head (though I have a big head). The earpieces are very comfortable though.
Summary: I bought these as a cheap option for noise reduction headphones. I wasn't sure how well the noise reduction but sat in my office with the computer noise and air-conditioning noise the headphones work perfectly. They are OK in terms of comfort and fit my oversized head easily. The simple control is easy to use and the battery hsn't run out yet so the battery life is a lot better than I would have thought.
