Summary: The noise cancelling on these Audio_Technica Quiet Point ATH-NAC7b headphones is indeed excellent, but there is a reason why they are so cheap. They suffer from RFI (Radio Frequency Interference) when in noise cancelling mode.
Pros: Great noice cancelling and good quality sound. When you turn on the noice cancelling you can hear the background noise dissapear. And then the RFI kicks in and you have to turn noise cancelling off!
Cons: Suffers very badly from Radio Frequency Interference., Suffer from presure build up.
Summary: Cons Cont: they agreed that the cracks were in stress zones and formed due to fatigue from frequent use. All I want is some headphones that won't break after 3 months. I went with these because they were supposed to be sturdy. I was completely happy with them up to this point.
Pros: Noise Canceling is amazing. I have friends with the comparable Bose model and have used their headphones and don't really notice much of a difference in high or low tones. Unless you know exactly what you're listening for, I wouldn't worry about losing out on any sound quality with these.
Cons: So I previously had a pair of noise canceling headphones of another brand I bought on another site. Come to find out, they had a manufacturing defect that caused the plastic on the headband to crack with use over time (reason they were on sale). I disappointed and took over a year to make that in...
Noise cancellation passable, transmission of cellular frequencies a no-no

Summary: I returned these headphones with regret. They are not as good as the Bose and they have the same flimsy feel of the Bose, but with using my phone as the sound source a lot of cellular digital noise piped into the headset. And for this reason I returned the headphones
Do not buy these headphones under any circumstances
