[CES 2018] Have you ever wondered what happens when the authorities seize/confiscate illegal firearms? There are several ways that they can dispose of them, but one of the more interesting ways we’re seeing is through the Humanium project, which basically takes illegal firearms, melts them down into metal, and reuses them for something else.

In this case headphone maker Yevo has unveiled the Yevo X Humanium headphones, a pair of wireless earbuds in which part of its build is taken from the melted metal of illegal firearms. “There are hundred of millions of illegal firearms in the world. As a result, someone is shot every minute. Armed violence is a global epidemic that hits developing countries especially hard. Humanium is a new material made of recycled metal from gun destruction programs. The metal is melted and moulded into units, which are then made available for commercial production.”

In terms of specs, the Yevo X Humanium is actually identical to the Yevo 1 headphones that was launched last year. They are similar in concept to wireless earbuds we’re seeing from companies like Apple and Bragi, and will feature a 60mAh battery that is good for up to 3-4 hours, and comes with a carrying case that will allow users to recharge the earbuds several times over.

The headphones also come with an accompanying smartphone app that lets users tweak the EQ, boost the bass, control audio transparency, and check on battery levels. We have yet to try the headphones out for ourselves so we can’t speak to its audio quality, but if anything it does sport a pretty sleek design. The Yevo X Humanium will be priced at $499 but if you can’t afford to spend that much, the Yevo 1 is priced at $249 which is half the price.
