I was excited to get another pair. The Bose iphone app doesnt do very much at all. The battery life is good and the noise cancellation does work. Mic quality is decent, auto muting when you push the mic half way up is incredibly convenient. I have problem feet and have tried on dozens and dozens of slippers. Short Version: I received to fair functioning controllers this round. It is not awful, but, if you have a road bike, its a bit too wide. Noise cancelling and very comfortable to wear. Believe it or not, the whole afternoon and evening went by without even thinking about my feet! --- This could be a high-paying job to American workers at these prices!
