Summary: After a week of use, I have been most impressed by the Noise Canceling Feature. The Bluetooth feature, read cordless, started the quest which ended on the Sony MDRZX750BN. (they need a more simple name) Using them daily in a work environment required a wireless function. The noise reduction is excellent, cutting out motor noises and still delivering sound clearly. I was not sure of the on the ear design, but I do not have an issue with it. Overall, 5 stars.
Summary: As soon as I put these on I knew they wouldn't work. The earpieces hung below my ears and they slid around my average sized head! I had my husband try them on (he has a large head) and they slid on his head too. Have no idea of the sound quality, but we found them to be unwearable.
Excerpt: I got sick of getting tangled up with the wire that my Bose Noise Canceling headphones came with. So I tried the MDR-ZX79BN headphones. The quality of the sound is great, and they block out noise very well. I am glad I own them.
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound, Lightweight, Stylish
