The JVC headphones work fine -- good noise cancelling, nicely portable, high or low frequency selection. Headphones are a highly personal preference. These are "on ear" which is not cited on the product description. I prefer the "around ear" style over the "on ear" or 'in ear" styles for best noise control and sound fidelity. I like the in ear style for extended wear. I find the on ear style to be a bit more prone to sweating and ear discomfort (pressure on ear) during the length of a movie..
I really like the JVC headphones. However, I don't think they deliver as advertised. Eventhough they have a good sound and nice bass, they are not noise canceling. i've put a batter in them and switched to noise canceling and the sousnd is no different from regular mode. I think this is a fair value for the money but not the deal that I had expected.
The headphones were exactly as advertised. Deliver was prompt. My only negative point is that they did not cancel out all of the outside noise. I purchased them to use in a special education classroom where I needed to be able to tune out all extraneous noise. If it were not for my intended use, I would highly recommend this product. PA
