*Muffled speech*
This poor guy. He looks to be connected to some life-saving device that breathes for him or provides oxygen directly into his lungs. Or be he’s suffering from halitosis and is wearing this gadget for the safety of his coworkers. All of these answers are wrong. This weird device supposedly protects your privacy while making calls by blocking sounds coming from your mouth.
This isn’t the worst gadget we’ve seen, though they could’ve made it more appealing. For instance, it could have been a huge helmet that you wear over your head. That’d be helpful for receiving calls while driving a motorcycle.
