NC:
is the same for both in order and in about. As the sound Bose around a track seemed louder, I'm assuming that NC works here better around a bit. But the real test next tram and car traffic in the restaurant I could see despite repeated changes between two no difference.
Sound:
In a quiet environment for me was the Sony Sound but audibly better (sound depth). In the subway, however, I could not hear the difference. Hiss and background when song changes, or I could not find similar in both.
Comfort:
Which is unique to me. As already written by another reviewer, "flattered" Bose ears. That's not the case with the Sony. The listeners are still pleasant, but considerably larger.
I really do not like heavy, but because the design and the joy of wearing are also an important factor for me, I have decided to use the Bose. He's just hipper, easier to carry and it gives me more pleasure to look at him. If there is little else audible differences, that's an indication ... but the choice was fairly scarce.
