The Yevo X Humanium wireless earbuds and charging case, made from recycled metal from gun destruction programs, are displayed for a photograph at the 2018 Consumer Electronics Show (CES) in Las Vegas, Nevada, U.S., on Thursday, Jan. 11, 2018. Electric and driverless cars will remain a big part of this year's CES, as makers of high-tech cameras, batteries, and AI software vie to climb into automakers' dashboards. Photographer: Patrick T.
