80% Noise Reduction
Contoured canal design
Maximum sound isolation
Monitor Function
Volume Control
The JVC Inner-Ear Noise Cancelling Headphone cancels up to an amazing 80% of background noise, and also features a unique contoured earpiece that's slightly angled, allowing a natural and secure fit that provides maximum sound isolation. Because of the superb ambient noise seal, precise acoustic coupling to the eardrum can be employed, thereby lowering the volume required to achieve the full sonic impact. They also feature a monitor function that allows users to mute the sound for conversation or listening to announcements. Provided accessories include three different sizes of ear pieces, dual-plug adaptor, soft carrying case, and one AAA battery which runs the unit for approximately 70 hours.

I've used both over the ear and ear bud style noise cancelling headphones and both have their place and function. I like these JVC earbuds as they are tiny, you can fit your ipod into the JVC case and they do work.
I read a couple other previous reviews which say these are either perfect or don't work at all. I'm in the 'they work, but not as good as 'over the ear' models' camp.
First comment, I don't think any of these (although I haven't tried the Bose) will eliminate all noise, especially things like voices or changeable frequency noises. What they do best is to eliminate or significantly lessen the constant / droning noises, like those of airplane engines. These earbuds do that pretty well.
Second comment is to experiment with the 3 earbud sizes they give you. I've found a significant change in effectiveness for each size (and for all us men of a certain age (and older), the trimness of your ear hairs will also have an effect.... sorry ladies....)
I used these on my last flight without any music playing and found a significant difference switching from the 'monitor' function (which stops the noise cancelling) to the active noise cancelling. It did take about 5 seconds for the noise level to decrease, which might give an indication of what kind of noises it removes, ie., those that are constant for a few seconds.
So, if you want close to concert hall, go to over the ear (and the bigger, thicker the ear covering the better), but if you want to substantially decrease the background noise level, these earbuds work just fine.

Lost my iPod and Etymotic ER6i earphones a month ago. Spend 10x longer trying to decide on what earphones to buy than on which iPod.
For both the cost reasons (I'm cheap - I drive a 1996 Corolla) and cause I lost the last pair, I didn't want to shell out $300+ on the Bose / Sennhieser, but did want something good.
Finally decided to give these JVC a try - even after reading the mixed reviews.
What a huge mistake. The noise cancellation doesn't appear to do anything. I thought maybe it was just me, or maybe it only worked with "white noise" type noise, so I downloaded a white noise generator.
Turning on / off the noise cancellation feature did nothing to reduce office noise, or white noise, with or without music playing. Maybe JVC has some test that shows it does this by 1db in some lab condition, but I certainly didn't notice it.
Purchased a pair of Etymotic ER6i's again - they fit better (and come with 3 cone (small / med / large) tips and 1 foam, so you can match your ears better, SOUND better, and don't have the awkward battery/circuit box that you had to rubber band to your iPod.
Wish I'd kept the packaging - I'd really, really like a my money back from JVC...

I use a Bose QuietComfort 2 and a Shure E3c-n Sound Isolating Earphones (Black); I thought that this might be a good, smaller, alternative to the Bose. Wrong. The JVC HA-NCX77 is useless. After using them for approximately 24 hours on 6 different flights I can state conclusively that they provide effectively no noise reduction beyond what you would expect from an in-ear set like the (much better sounding, more effective, and higher priced) Shure. Most people will probably be better served by just sticking their fingers in their ears for 4 hours ;-)
Congratulations to JVC on a good marketing launch for a worthless product.
Update (17 Aug 07): After seeing a few positive reviews here, I thought it would be worth exchanging them to see if a I had a bad set. I received a new pair from JVC, put in fresh batteries, re-read the manual, and used them on a trip from Boston to London. Exact same result ... Their noise cancelling is completely ineffective.
It's absolutely beyond me how anyone can give these a positive review; I can only conclude that they've never actually used a device that provides effective noise cancellation as opposed to simple passive isolation (e.g. the Shure E3c)
For the reviewer who said the Bose are too expensive, I agree. Try the Audio-Technica ATH-ANC7 QuietPoint Active Noise-Cancelling Headphones. They're at least as good as the Bose, possibly better, and are about 60% less expensive.
