 Works well but don't expect magic February 17, 2006

Surprisingly these earbuds work quite well. Now that the price in reduced to under $100 they are a much better deal. Don't expect pure silence. However do expect to be able to listen to your content at half the volume you are used to using.
Most of the noise reduction is passive, simply the rubber fittings on the ear buds make a seal with your ear hence blocking out a lot of sound. It is crucial that you try the different sizes to find one that gives you the best results. The active (electronic) noise cancelling works well on the low rumble on airplanes, the sound of a car heater or the sound of an air conditioner. Other than that the active noise cancelling does not do too much.
The sound quality is good provided the earbuds fit you properly.
One issue is that the sound the chord makes vibrations that travel up the chord and since you have a tight seal between the buds and your ear you will hear a lot of that. so dont use these for jogging. then again the bose quiet comfort 2 had a similar problem although nto as bad.
If you happen to travel by BART on the S.F. Peninsula then these earbuds are definately effective. You will still hear the 'sounds of hell" screeching (again dont expect magic) but it is very much subdued and you will be able to listen to your iPod at half volume.
Another point you can not compare noise cancelling headphones with regular headphones. that's an apple vs orange type comparison. For $100 you can get much better sounding headphones but they will not be noise cancelling. I would say just for sound quality alone a $40 pair of non-noise cancelling ear buds would sound about as good. so ya you do pay for the noise cancelling features.
If you do not need the noise cancelling functionality then I would say do not get these, because dollar for dollar regular earbuds will sound better and be more comfortable.
 These are not that good, I'm returning them. March 15, 2006

The Sony instructions state that these work most effectively on lower frequencies. I found that these do not really work that well in any frequency range.
My first test involved sitting in the airport terminal with the headphones on, and turning on and off the noise canceling feature. I could not distinguish any difference in background noise during this test.
My second test involved turning on and off the noise cancelling feature while in flight. I did notice that the sound of the engines was decreased slightly, but not enough to make me want to keep them.
I later listened to another person's over the ear style noise canceling headphones, and they were significantly better at reducing the background noise of the plane.
Thankfully, the place I purchased them from will let me return them.
Good Size-Performance Combination June 3, 2004

If you're looking for maximum noise reduction, go for the over-the-ear headphone. However, I take my laptop and assorted peripherals with me when I fly and I simply don't have room to store full-size headphones in my carry-on computer case. I purchased these earphones during a business trip a couple of weeks ago, and I've found them to be a good alternative. They're small, but deliver good performance for their sizeI wasn't too impressed with them when I tried them in the airport, but my first flight with them was in the back of a 757 and I was surprised at the amount of engine and background noise that they cancelled out. They definitely made the flight a more relaxing experience. A couple of observations: 1. Make sure you get a good snug fit from the earbuds. If they don't fit snugly, the noise cancellation effect is significantly reduced. It may take some experimentation with the 3 different sizes Sony includes. 2. Once you turn the power on, it may take a few seconds for the noise cancellation to reach it's maximum effect. 3. The earphones don't block the sound of your own voice like the over-the-ear headphones do. In fact, they seem to amplify it. (But then, you're normally not conversing with anyone while listening to music or watching the movie.) All in all, it's a good value for the money if you spend a lot of time on airplanes and don't want the hassle of carrying the bulkier over-the-ear headphones.

When you read the specification of how these are meant to work, they do 'make sense'. However this is probably not what most people - myself included - are/were expecting when they read noise cancellation.
1)These are in-ear. Sitting at home with these in, there is no difference with NC on or off. The fact that they are tight in-ear plugs blocks out the majority of the noise!!!
2)NC: 70Hz - 1000Hz. Haha! If I knew this when I asked Santa, I would have changed my order. This is basically low-level background noise - walking along a street there is reduction in transport and background noise, everything else gets through - people speaking.(But the plugs do reduce the majority of this).
3)Used them on the commute in by train (not bad - a definite improvement).
But now for the science - it is not the noise cancellation that causes this improvement. It is actually the low-level hiss!! This hiss is not anti-noise - I would guess that it is (10db) white noise. Which if anyone who understands audio knows the ear/brain will start to ignore after a while.
The audio signal is amplified and you get a ~10db (70Hz-1000Hz) white-noise overlay. With the earplugs blocking the majority of the noise.
Very clever, a practical engineer's solution.
Noise reduction yes but not noise cancellation.
There is no hiss in proper-noise cancellation - period! Feedback problems perhaps, but not a continuous background hiss.
So they do allow you to hear your music better by blocking most of the external noise and then tricking your ear into ignoring the lower-level frequencies. This will be an improvement in a few situations.
Also, the wires suck - absolutely - poor design. Someone will strangle themselves one day. They suck so bad that my next headphones will be wireless (bluetooth).
2 stars for marketing - none for technology!
 A compromise product that by nature is mediocre in many ways April 22, 2004

If you buy these expecting the same kind of performance as a pair of over ear noise cancelation headphones you will be disappointed. They in no way perform on the same level as the bose or even the less expensive panisonic models. On the other hand they are earplugs and can quite easily fit in your pocket. If you are like me and use your player on the subway a lot they are pretty close to ideal. Granted that is a pretty narrow functional range but for commuters this is a solid product. I disagree that the noise cancellation does "nothing" as some reviews state, though again it is nowhere near the same level as the full sized devices. You will not notice the hissing unless you are in a quiet area - and you are able to turn the noise cancellation off in this setting. I am able to keep myy player at a much lower output level with these headphones which both conserves batteries and my ears so it was a good purchase for me. The only 2 other draw backs are the ridiculously long cord - 4 feet? - and the price. Im not sure if these are really worth 90-100$. For 50$ Id feel super comfortable recommending them, but at this price point you might be better off with a less expensive pair unless you find yourself commuting a lot, and still not wanting a full sized pair of noise cancellers.
