Summary: My problem obviously has not happened to many other folks, so you might love them!
Pros: They sound really good and canceled the fan noise from my HD projector quite well.
Cons: After watching a movie for 50 minutes the night before, I woke up with a ringing in my ears the next morning. A kind of a faint version of what happens after going to a club with really loud music. I'm paying the restocking fee to return them!
Excerpt: As the sales pitch says, these headphones really do offer great sound and effective noise canceling, and are more than comfortable for a cross country flight. BUT - the 4 foot stereo mini-phone plug to stereo mini-phone plug cable that connects the headset to your iPod/CD player/etc. too easily disconnects from the headset, and when you lose it, JVC wants [$] - yes, [$] - to replace it!
Summary: This is the first review I have left on Amazon, but thought I should share my opinion as I personally find the reviews really helpful. Overall I was quite disappointed with these headphones, in fact, after a few hours of use at home, I decided to return them. Firstly, I didn't find the on ear design very comfortable. I found my ears felt quite squashed after a short period of use, and felt relieved when I removed the headphones.
Summary: In short: They are good, but next time I want to try something else. The usual caveat is, don't expect that this kind of devices will isolate from anything around you. I find them useful in two situations - moderate noise, like on the train, good for commuting - enable comfortable conversation when on traffic roads, you will be able everything the other person says on the other end They are not good in two other typical situations: - in the underground the noise is so...
Summary: Wanted to replace a previous purchase of noise cancelling headphones. (previously Bose QC3 - had two pairs in 6 months both stopped working, with the left speaker giving out no sound) After much research I bought these as they were highly ranked on one of the review websites, and less than half the price. After using, I couldn't hear any benefit to switching on the noise cancelling? All it did was amplify the volume. Basic sound quality was also poor in my opinion.
Summary: Aunque la calidad de sonido es muy buena, resultan tremendamente cómodos y confortables, la función de cancelación de ruido no es en absoluto efectiva; es más se percibe un ligero ruido adicional producido (supongo) por la electrónica interna.
