Product DescriptionThe HA-NC250's noise cancellation circuitry includes feedback technology that constantly monitors the noise cancellation process. As a result, the headphones eliminate up to 85 percent of extraneous background noise. To further block noise, the HA-NC250 offers two JVC innovations that help isolate the listener from outside sounds. First, each earpiece employs a double housing structure for an extra sound insulation layer. Second, JVC developed a technique for attaching the headphone's smooth memory foam cushioned ear pads to the housing that helps isolate background noise. The smooth pads also enhance comfort. These sound isolation features, for which patents have been applied, are especially important since the HA-NC250 can be used with the active noise cancellation switched off.For the best possible sound quality, the headphone uses a 40mm neodymium driver in each earpiece. For comfort and portability, the JVC HA-NC250 is one of the lightest headphones in its class, weighing just 5.3 ounces. It folds flat, and when folded is slimmer than most competing models. Included with the HA-NC250 are a slim carrying case, a four-foot detachable cord, airline dual plug adapter, and 0.25 inch plug adapter for use with many home audio and video components. The headphones use a single 1.5-volt AAA battery for powering the noise cancellation circuitry.
High Quality, Reasonable price. (Rating: 5 out of 5) Similar to Bose, but affordable to the average consumer. I've used them everywhere and have been very impressed. Noise cancellation makes a noticeable difference.
AWESOME (Rating: 5 out of 5) I'm a professional audio guy and these headphones rock. They sound great with the noise cancelling off, but turn that bad boy on and hot damn they sound amazing.
Excellent Sound but they hurt my ears. (Rating: 2 out of 5) I tried these out on a long flight and the sound quality is amazing. The noise cancelling works very well. However, the on-the-ear design hurts my ears after wearing them for about 1 hour. I returned them after this trip and will end up trying an over-the-ear type.
husband says they work great better then his last sennehiser (Rating: 5 out of 5) he says they were better because they were so much more comfortable on his ears. so im giving them 5 stars
Very good quality headphones (Rating: 5 out of 5) I was initially very impressed with the quality of these headphones when I recieved them. They seem very well built. I looked at some Sony's that were flimsy in comparison. After using them for a while I continue to be very happy with them. Sound quality is good and they are very comfortable. I initially wanted an around-the-ear headphone but decided on these (over-the-ear), I'm glad I did. They are very comfortable. My previous Sony around-the-ear headphones would hurt my ears after using them for a couple hours, these don't. I tried on some Bose around-the- ears also, and they were so firm it felt like my head was in a clamp (good sound quality but expensive).
Another thing I like is the carrying case and the fold flat design. The carrying case fits nicely into my computer bag and there is enough room in it for my 8GB Zune and cables.
