As specified by Microsoft, to use Cortana on Xbox One you either need to have a Kinect or a headset microphone.

As much as I love Kinect, it can be expensive to purchase as a standalone device, particularly since it's no longer in production. Since the new Xbox One S comes with an IR blaster built in, you may find yourself even less likely to want a Kinect unit. Additionally, if you have invested in a dedicated sound system, donning a headset just for Cortana might seem a little counter-intuitive and silly.

But if you have the revised Xbox One controller with a built-in 3.5mm headset jack, there's an easy and cheap method for activating Cortana voice commands on Xbox One.

Amazon is crammed with mini-microphones designed for use on smartphones with dictation software. Thanks to the standardized 3.5mm jack, the Xbox One will detect these discrete mics as a headset. Attaching them to your controller will allow you to activate Cortana commands without purchasing a Kinect or dedicated headphones.

If you search Amazon for "3.5mm smartphone microphone" dozens of options that should work with your Xbox controller. But you can hit the links below for a look at our favorites.

It's worth noting too that Microsoft is exploring bringing Amazon Echo to the console, which would completely replace the need for an additional microphone to interact with your Xbox console. Echo devices start at just $40, and we'll be sure to let you know what (and if) that integration goes live.
