To summarize: this is very good pair of noise-cancelling headphones that do the job at least as well as any other headphone out there (particularly Bose QCs which I had a chance to try in the past), but a half or third of the cost of the more expensive ones. My research before buying suggests that $100-150 is the actual reasonable price range to get good NC headphones today. Anything over that makes very little sense and is a waste of money.

What I found is that these headphones successfully cancelled out the low- and low-mid frequency noise of the engine. It does not mean you hear nothing altogether - there is a "white noise"-like background - but the 85% figure in JVC specs seems to be about right. Once the music is on, you barely notice that.

They did a great job of lowering (although not eliminating) the awful engine drone of the jets. I was disappointed that this new model doesn't have the retractable cord that made the previous version so convenient, but the technology is great. The earphones eventually grew painful to wear after several hours, but careful adjustment seemed to alleviate the pressure on the ears.

However, the cord or jack would not make a connection to the headset. If you wiggled and pushed in the cord at the same time, you could get a second or two of music -- that is all. I got my money back and bought a Bose noise cancellation headset and have been very happy with the Bose product.

My wife just took them on a 16-hour flight (that's in the air 16 hours non stop) and never took them off and felt no discomfort. With noise canceling on the JVC are better then the QC3 with good tight bass, clear mid range and crisp high end not as sparkly as the QC but more similar to the Bose non noise canceling over the ear headphones. The JVC will work with the noise canceling off (in case you run out of batteries) the Bose will not but the sound quality will suffer.

It is a good noise cancellation phone, especially it does not generate hiss between track as most of other noise cancellation headphones have. Also it works without battery, a nice feature Bose does not have. It is comfortable, maybe not as comfortable as Bose, but still good.

I took them back today, I had high hopes for them. I would say they would be ok for a $69 price. Eventually I could see the tabs that hold the ear piece on over the battery will be prone to breaking off.

My pair of Grado SR50 headphones recently failed after 7 years of service, and I needed a replacement. Further, I was becoming increasingly distracted by the noise at work, and needed a way to reduce it. I own a very cheap pair of noise-cancelling headphones already, but they create a constant hiss when enabled, and quality-wise were no match for the Grados.

My only concern is the placement of the battery, where replacement may result in your breaking something off - you have to be careful. One note: In some reviews there was a mention of an air-popping sensation when NC is on. Amazingly enough, I got to experience that the first time I wore the headphones, but it turned out to be strictly a matter of headphone placement on the ear, the fit.

Switch on the noise canceling and something strange happens all the low frequency sounds just vanish fridge, furnace or in a plane the jet engines you can still hear the kids and TV (till you switch on the music). The other big difference for me is I feel no audio pressure and I have kept them on for hours. Bose with the QC3 eliminates a much wider frequency range then the JVC but introduce much greater audio pressure in the process.

The downside for me is the extreme audio pressure exerted by the noise canceling on my ears and I can't keep them on for more then 15 minutes (I feel the discomfort in 15 seconds) but every one is different in their tolerance. Now to the JVC HA-NC250 with an over the ear design but slightly larger then the QC3 the JVC ear pads do a very good job of dimming the sounds. But with noise canceling off you can hear most common sounds (kids, TV, fridge, furnace).

Good sound when NC is on, even though it may not be as good as some of non-noise cancellation headphones like Grados. After a few weeks, I still like this device. Even in non-noisy environment I sometimes turn NC on just to enjoy different characteristics of the headphone.

I ordered these JVC headphones after testing the Bose and discovering they only work when the noise reduction is switched on. The JVC build quality is great, fit comfortably on the ears and work well with or without the noise reduction.

I do not have anything to compare against directly, but the Bose headphones I've tried in the mall do not seem to work any better, cost more than twice as much, and have a less convenient battery situation.

My only real complaint, and the reason for 4 instead of 5 stars is the design of battery placement. To replace the battery you have to take off the ear pad from the right earpiece.

First all noise canceling headphones will produce some audio pressure in the ears and this is simply to do with way noise canceling works. Neither the Bose nor the JVC produce any annoying amplification hum found in many noise canceling headphones. The Bose QC2 are over the ear and just the physical design cuts out a large amount of ambient noise, the active noise canceling takes care of the rest.

Though you won't get the envious looks from other passengers that you would with the Bose but for about the cost of one QC3 a family of four can have the same comfort and sound quality as you get with the Bose. At the same price I would take the JVC NC250 over the QC3 but at a fraction of the cost this is not even a contest the JVC wins.

Considering its on-ear design, that is remarkable in my opinion. At the same time, they do reach a nice seal on the ear. The padding on the earpieces and the headband help that a lot.

I found it annoying. As headphones they worked better with the noise canceling on I supposed because of the power boost. With the noise canceling off, the volume needed to be turned up.

I recently purchased the JVC HANC250 headphones after researching the options on the internet. The Bose were an obvious option, but the price could not be justified.

The noise canceling works well but you have to put extra battery for this function. and only cons for this headphone is the battery life. I didn't compare the other product battry life but I "feel" it dies fast.

I was also hoping to be able to get great sound while I used them. Unfortunately, you either get noise AND your music or you get silence. And no matter what i did, my Mac didn't recognize the headphones and so whether on or off i got no sound from my audio device.

I got these for work where it is a noisy, shared environment. Unfortunately, the only sound it seemed to cancel was the noise caused by having my ears covered.

Well she loves them: they are comfortable, cut the worst of the plane noise, and the sound is excellent whether listening to the airlines' movies or music player. My problem is that I travel too and she wont share them!
