The way we listen to audio has evolved with technology. Headphones, once bulky skull-huggers that kept us plugged into a device, are going increasingly wireless.

On this week's episode of The Gadget Lab, Mike, Lauren, and Arielle take a look at the ways we use tech to listen, and how our tech listens to us.
