Pros: I use them while flying and am very pleased. They remove background noise very well. You can still hear other passenger voices but I have yet to find any noise cancelling headset able to remove that.
Cons: The cord could be a little longer but they are still very usable.
Pros: After opening the package, I immediately went and stood by my woodstove, with the external fan turned as high as it would go. The earbuds fit snuggly in my ear canal, blocking a good amount of noise on their own. I then cycled the power switch for the noise cancelling on, then off about 3 or 4 times. I'd say the electronic noise cancelling cut the noise level by 65-75%. Certainly a significant amount. Like many others, I will be using these for outdoor work, the major...
Cons: The compartment for the battery should be further up the cord, or further down. It has a clip on it, but it is too short to reach your beltline, so it hangs and tries to pull the earbuds out.
Pros: They fit well, and the rubber pieces you can attach for securing the phones over-the-ear is useful. The sound is fine.
Cons: I was unimpressed with the noise reduction. I got these to use on airplane flights, and I found the noise reduction barely noticeable. A better choice for noise reduction is the audio-technica ath-anc3.
Summary: If this was meant to be a belt clip, you would have to be 3 feet tall. The noise reduction is negligable. I bought this instead of the Sony. I got cheap, WRONG! Sony sounds better with grest NR. Better ergo too. I know I had 2 Sonys. Stepped on one, and broke the belt clip on the other.
Pros: Build seems ok.
Cons: Very short cord from the main section (battery/electronics/clip)
Summary: JVC makes some wonderful products, like the on-ear NC250. The NCX78 does not deliver.Placement in the ear is awkward. Sound quality is average.Most importantly, since you're buying these for active noise reduction, I couldn't discern any difference when the active noise canceling was turned on. The only consolation is that the Sony NC33's are no better, and they cost three times as much.
Summary: I definitely agree with the other reviewer who said the highs were strident. The high frequencies really don't sound that great through these headphones. They sound like they are too loud. It is more noticeable when there isn't much background noise. With a lot of noise it seems to balance it out.
Pros: I love these headphones. The standard earpieces are very comfortable and stay in my ears very well. I like the detachable ear loop too.
Cons: Like all noise cancelling headphones they don't do a very good job of cancelling out human speech. Don't expect them to silence everyone around you. These headphones are best with low frequency and repetitive noise like engines and motors.
Pros: As you may already know, the main pro is the active noise reduction. It does what it says, and I am very impressed at how much it actually cancels out. It cancels out mostly the lower frequencies, such as the appliance hum or wind. I use these when I fly, slip them in under my headset, making it a cheap alternative to active noise reducing headphones. They cannot effectively cancel out the human voice, which makes them ideal for listening to the air-to-air communicati...
Cons: At higher volume, the bass on these tend to cancel out all other parts of the song that I listen to, making it quite an annoyance. Other than that, These are 5-egg worthy.
