Summary: I am no audiophile so take this for what it's worth. I was using UE6000s, which are great-sounding but the NC is poor. These destroy the UEs in NC and might sound a little better (wider soundstage). They do not match Bose in NC. The case is large and I'm unsure I would carry-on such large item on a flight just for the NC.
Summary: I use these headphones at every opportunity I can, which usually means in the office or at home. I listen to indie/alternative rock and EDM, and I think these headphones are versatile enough to provide me with the sound I'm looking for in both genres. The case allows for easy transportation without fear of accidentally scuffing/breaking the headphones. Also don't hold these badboys back--pair them with a headphone amp!
Summary: I haven't had the chance to use it on a flight yet but I have tried it on at home in front of the tv. My first impression on these headphones I would say they are pretty good. It blocked out most of the noise from the tv. The sounds that comes out of these headphones are pretty amazing! I would recommend these over the bose qc-15 just because it has better sounds. As far as noise cancellation, I would probably recommend the bose over these.
Summary: Really, really good. Very good at cancelling noise - even a loud diesel engine is reduced to a faint murmur. Also very good at MAKING noise - at least on par with my studio monitor headphones. Very comfy - I regularly use them for 2-3 hours at a time and usually forget I'm wearing them. Super, super chuffed with them. Handy that they can be used without power, but be aware that they sound pretty lame in comparison to when the power is on.
Summary: Having recently been diagnosed with Hyperacusis, a low tolerance of loud sounds, I purchased these to use on a flight to Croatia. Once settled in my seat I put the phones on and there was already a reduction in noise from the passive effect of the snug fitting ear pads, but when I switched on the active noise cancelling circuitry I was absolutely astonished by the peace which descended on me. A big smile came over my face and a wow from my lips, these things are amazing.
Summary: After intense researching on many sites and knowing the fact that Bose are the best; I chose to buy this one. While I came to know that Bose QC3 has laughable Noise cancelling; I wasnt very impressed with Bose QC15 reviews either when it came to compete with this Audio Technica Headphone.
