Excerpt: I use these while playing/recording drums. It is heresy to some to use noise-cancelling headphones while tracking. I don't care. I love these. They isolate me very well from bleed-through from the drums as I'm playing. Through the headphones I hear what's getting to the microphones much better because they isolate so well. And I don't have to turn up the volume on the headphones near as much because they cancel out the external drum noise so well.
Pros: Comfortable, Good Bass, Good Value, Great Sound
Excerpt: These Audio-Technica work better than the Bose. We have 3 loud rotory drive chillers in our power plant. We bought the Bose noise cancelling head phones 8 years ago. Now we have the Audio-Technica noise cancelling head phones, and there is a difference. Also the price is a whole lot less than the Bose.
Pros: Comfortable, Durable, Good Value, Lightweight, Makes Me Look Good Too
Conclusion: Love these headphones! I can wear them for 9 hours straight at work and they are still super comfortable. Noise cancelling works well and makes music sound even better when it is on. I definitely recommend these to anyone and everyone! Definitely a necessity if you work in an office.
Excerpt: Very comfortable. They goes over entire ear, so they block large chunk of noise just by that. NC is not intrusive. Compare to headphones from company which "makes better sound through marketing" ATH sounds superbly. If you do not want to sacrifice sound quality for NC, this is perfect choice. Down side - they are quite big. But they come with very nice semi hard case, they work on AAA (which last quite long) and comfy on train or plain.
Summary: Excellent, I love them and the flexibility offered by the three modes. My main suggestion is not to buy them in the UK (£200 or so). Rather, buy them on Amazon USA for more like £120. Then they truly are worthwhile - especially if you can avoid the shipping costs by buying them when you are on holiday there, or get a friend to bring them back.
Summary: I have been using them daily since they arrived on my commute and at home. These headphones are quite frankly the best I have ever owned. Super comfortable for long periods and just a joy to listen too.
Summary: Excellent product. Perfect balance of price and quality. Sound and noise cancellation both A grade. If the battery is dead they still work which is a bonus over other active noise cancelling brands.
