I ordered these headphones thinking the switch in the middle has a volume control.

I got desparate just before taking a long flight, and purchased these for about $30. They did a good job of cancelling background noise on the plane, and for that purpose, I would highly recommend them. They even come with an adapter for jacks that require two plugs instead of one (like US Airways).

Overall, they sound pretty good. As with most earbuds, to get good bass, you need to make sure they are snug inside your ear.

When you turn on Noise cancelling, the volume increases, and this is typical because Noise Cancelling works by amplifying the sound and "subtracting" the outside noise that is being picked up. With a standard AA battery, you can get several hours of Noise Cancelling. When the battery begins to die, the volume actually drops, and it is much better to just turn Noise Cancelling off.

The earbuds fit well (there are 3 sizes included) and help to block a lot of external noise, so even without Noise Cancelling turned on you can block out of lot of unwanted noise.

And here is where Philips went wrong...They made the cable nearly 4' long (1.2 Meters), but in the middle, there is the bulky Noise Cancelling switch that holds the AAA battery. Not a problem when you are sitting (eg. on and airplane, or at work) because you can just set it down. But for example, when you are walking, it hardly reaches your pants pocket, so you can't stand up straight, or it will pull the buds out of your ears. Leaving it hanging will do the same thing. In fact, this has been such an annoyance to me, that I never use these anytime I'm being active. And it's a shame, because they do a good job of cancelling lawnmower noise.

Verified Purchase
I bought these earbuds to help combat some of the sounds that were bothering me at work. I'm a cubicle dweller and there are some noisy folks in my neighborhood. I wanted to block out voices, phones ringing, photocopier noise, etc.

These earbuds work pretty well and are reasonably priced. I find them comfortable to wear and they even help block some sounds without the noise canceling turned on. The rubber cups work like earplugs, so I can listen to my music at a lower volume and yet not be bothered by external noise.

I do hear a little "white noise" along with the music when the noise canceling is switched on, but it doesn't bother me. With noise canceling turned on I think the music sounds better, the volume is boosted a little but not super-loud.

I've also tried using these in the car and they block out traffic sounds, open windows, etc. pretty well.

I am happy with this purchase. If I'd had very high expectations I would have bought one of the top-of-the-line, super-expensive sets of noise canceling headphones. I just wanted something comfortable, effective and inexpensive, and these earbuds delivered that nicely.

It appears most of the reviewers who found the noise reduction ineffective were testing it out in normal listening environments such as a home or office. The NR will not be noticable for this use, as it primarily works on the low frequencies. All you will hear when activating the electronics is a slight increase in volume & associated hiss. I also thought the NR wasnt working, so I took my mp3 player to a laundromat and put them to a test. The NR worked very well in reducing the low frequency washer & dryer rumble. The 70% figure seems about right, but only on the lows. I am a professional musician & recording engineer, and was very impressed by these phones. 5 stars, as they are a fraction of the cost of similar Bose units.

After sampling and rejecting several modestly-priced headphones, I've finally found some that are even better than the quite-good ones that came with my Creative Zen Touch MP3 player. The first moments were unimpressive, but I had not pushed these earbuds in snugly. Once that was done and I flicked on the battery-powered sound enhancement, I smiled. Crisp, clear highs, and sufficient lows, combined to delight my auditory nerves.

The need to replace one AAA battery and to manage the in-line noise-cancelling box (which fits nicely in one's shirt pocket) may bother some, but for price, compactness, and performance of these headphones, these two things are only slight detractions. I recommend them.

These phones do block noise fairly well but it's mostly because the rubber buds seal the ear and not because of the active noise reduction circuitry. I did A/B comparisons using a test tone generator at several frequencies, switching the active reduction on and off. There is some noise reduction at low-mid frequencies but it's quite marginal -- by ear, probably about 3 to (at most) 6 dB. The phones also add a pink-noise "hiss" that can be mistaken for noise reduction. These phones are not really bad; just don't expect too much in the way of noise reduction.

I bought these for use in my Jeep. They do a terrific (and very noticeable) job eliminating wind noise from my soft top (and my usually open windows).

They also have terrific sound compared to regular headphones in this price range. I hate hiss, but the tiny amount they add is unnoticeable when the are being used for their intended purpose. (In a quiet environment, I go back to my Philips Surround Sound earbuds.)

If you look at the specs for noise cancelling headphones, you'll see that the active cancellation handles low frequencies (50-1500Hz). Higher frequencies are eliminated primarily by the earphone/headset physical design itself.
