Microsoft's wireless Surface Headphones are all about Cortana

Lots of the news from Microsoft's Surface event leaked ahead of time, but we didn't necessarily expect to see these new Surface Headphones today. As you might expect, the main draw here is that Cortana is on board and easily accessible, but there are some other impressive specs here as well. Microsoft went with over-the-ears design which offers active noise cancellation; the company says it has 13 levels of noise cancellation all told. There are four beam-forming mics and four active noise cancelling mics as well as 40mm drivers. The Surface Headphones work with any Bluetooth-enabled device, so if you work across Mac and Windows or happen to use an iPhone, you're covered.
