The Electronic Fox Ears helmet is a listening device that changes its wearer’s experience of hearing. A pair of head-mounted, independently articulated parabolic microphones and built-in bone conduction transducers allow the wearer to sharply direct their attention to faraway sound sources. Field recording and ambient sound have long been a part of electronic music; our device extends these practices by drawing on a tradition of wearable technologies and prosthetic art that blur the boundaries of human perception.
