When your environment makes listening challenging, mobiWAN helps you communicate—by directing voice calls through your head. The headset speaker and microphone, created by Mobilus Labs, works through bone-conduction technology, transmitting sound as vibrations in the wearer’s skull. This allows workers to remain in communication with one another in conditions that are too noisy or chaotic to allow speaking over a phone or radio—think construction sites or a ship in a howling storm. “You can still hear someone talking clear as day,” says Jordan McRae, founder of Mobilus Labs. The headset ($490 per year for hardware and software license) launched in October, though the company has been testing it with the British Army and National Health Service. —Alejandro de la Garza
