Recent articles (including http://www.macrumors.com/2016/01/07/iphone-7-thinner-waterproof-no-headphone-jack/) have raised the prospect that lightning will be the main audio option for iOS devices. Lightning allows not only digital transmission of audio from the device to the connected speakers, but also of power and information, potentially information from the speakers back to the iOS device, if I'm not mistaken. That seems to (as discussed in the article) be very friendly to making noise cancelling headphones. And if much of the cost in expensive noise-cancelling headphones is in the components of the battery and processor, noise cancelling headphones using lightning should be cheaper (or shift their value to other components like mic and speaker quality and design, etc) since the iOS device's battery and processor can power the headphones. The question is (as lightening has been around for so long) where are these wonderful headphones!? And when will they come? (I know there is that philips one, but who knows about how that compares to Bose's NC performance, and I'd like something a little more compact a la the QC20) Discuss!
