A great buy for the price

Just received my JVC HA-NC100's yesterday and I am trying them out at work. My initial response is that they work as designed. In fact my co-worker just had to get up from her chair (she is 12 ft away) and said she was calling my name and I didn't hear her. So, for the purpose of me buying them, it seems to have passed the test. I tried another co-workers' Sennheiser PXC 300's before I bought these. The main difference I noticed between the two is the sound quality of music. More stereo quality sound with the Sennheiser PXC 300'S, but the sound quality is still good with JVC. I noticed that the music is affected when you turn on the Noise cancelling feature, but it really blocks out the background noise. The headphones are very light and portable and I love the retractable cord feature. If you are looking for a set of headphones that come from a good quality brand name but do not want to pay the ridiculous price, I would recommend the JVC HA-NC100. I do not buy a lot of things for myself, but a pair of NC headphones was a must. I did my research and decided these would be the best quality for the price.
