    By Ronald K. Goodenow on November 10, 2008
    I travel a great deal and have a drawer full of noise canceling headphones by Panasonic, Kensington, JVC and Sony. Each had limitations -- not enough high end, poor construction, poor noise reduction, or in the case of lesser Sony's I bought several months ago, pretty good sound, but rather inadequate ear cups and poor portability (they wouldn't fold up to occupy as little as possible space in my briefcase.)Always worried about losing or damaging something while traveling I did not go for the full kahuna and buy Bose.

    So, having seen these around some local shops and taken a listen I bought the NC40 and immediately took them on a trip.

    By and large they are fine. When turned on (don't even try to listen to them when off) the sound is rich and clean; lovely base and good high end, which is important to my tired ole ears. Plenty of mid-range. Nice volume. I'm not sure they are world beaters in terms of overall noise reduction, but they certainly take the edge off and from my same old seat near the rear of a Southwest jet, they provide a relaxing and easy to take listening experience. One WANTS to use this extremely comfortable headset, whether noise reduction is needed or not. I hear things I didn't know my MP3 decoder put in a file. Oh, I listen mainly to jazz and classical music.

    Oh yes, they fold up neatly and I like the on-off switch/battery holder, which lives by itself on the connecting line and has an override button that works beautifully.

    I find it funny when I read other people's reviews and they complain about the sound of these units with the power turned off. These units are noise canceling headphones. They were not meant to be "hi-end listen to all your music all the time type of headphones." There are tons of other headphones to choose from that will surpass the performance of the Sony MDR-NC40 for everyday use and for a lot less money.

    The NC40 are a noise canceling headphones. They were meant to cut the constant drone of airplane noise or the constant sound you get when riding in a bus or a train... and they do work.
    I guess what I can honestly say is if you travel 5 or 6 times a year on a plane then this is a great choice. I have not listened to the Bose models, but I can tell you this, no matter what I can afford, there is no way I could justify 3.5X the price for the Bose headphones to travel with a few times a year.

    The NC20 sits on the ear, it does not cup the ear. You can still hear when people talk to you at normal levels. If you are dealing with a screaming baby behind you just crank up the volume of whatever you are listening to and it will drown out the unwanted sounds.

    These are great if you use them for what they are intended. You can buy the NC40 here on Amazon and then get a set of Bose TriPort Headphones for regular every day listening and still be at less than 1/2 the price of the Quiet comfort headphones.

    The bottom line is I would recommend the NC40 to anyone who travels, but not to some one who just wants headphones to use at home.

    As a frequent business traveler, I was looking for some noise canceling headphones but did not want to spend the chunk of change on Bose. After reading some of the reviews on these Sony's here and other places, I decided to give them a shot. I'm glad I did! Now, I'm no audiophile, nor do I have much to compare these to from a noise canceling perspective, but they do their job well. Yes, you have to have them turned on for them to sound decent, but the battery life seems very good. I've made 3 trips to China and a few domestic trips with the original battery still in them. Probably 60 hours conservatively (I only use them on the planes). I can keep them on for a 13 hour flight with out any discomfort, and I am very pleased with the degree of noise canceling.

    I've had these headphones for about 9 months. I wanted to wait to review them, because headphones sometimes fall apart and this is obviously relevant to their value. And while this set isn't on the high end price-wise, it isn't cheap either. But I can say that I have had no problems with them so far.

    I've always had a love/hate relationship with headphones. Yes, I love them for the music, but there's always something about them that is uncomfortable or obnoxious. I listen to music while in transit, so I need a pair that is comfortable, but most headphones don't seem to be designed for comfort! Comfort means: doesn't hurt your ears to wear, and doesn't slip off. But this is usually a tradeoff; it's so difficult to find headphones that aren't a nuisance to wear in one respect or the other.

    In fact, for a while I wore earbuds because they tend to hurt less than headphones for long periods of listening, and they don't slip off if you have them in securely. But the problem is I found that although they wouldn't slip, they'd get yanked off easily if my arm or another object brushed the cord. I also tried a pair of "in the ear" headphones and the problem was any movement of the cord transmitted up into my ear, which was very distracting.

    I have none of these problems with Sony MDR-NC40. Actually they are very comfortable, so comfortable that at work I couldn't wait for a break to put them back on. The padding feels great, does not put painful pressure on the ears, but is snug enough that the set stays on if you lean forward or back. And while I won't say that they're the coolest option in the summer, they are very light so they are cooler than larger alternatives that can make you hot.

    The sound is really great.
