Earbuds can drown out lifesaving warning signs. But SORI is a new earbud that detects the sound coming from behind the user on the street, even while the user is listening to music. In Korean, SORI means sound. The earbud detects soundwaves as around the user, and vibrates to alert the user of dangers on a busy street.
