1. An earbud comprising:
a gestural sensor configured to detect movement data indicative of a gesture being performed by a user;
a first electrode positioned to physically contact a concha of an ear of the user when the earbud is worn by the user;
a second electrode positioned to physically contact a tragus of the ear when the earbud is worn by the user;
a third electrode positioned to physically contact a triangular fossa of the ear when the earbud is worn by the user; and
a controller coupled to the gestural sensor, the first electrode, the second electrode, and the third electrode, the controller programmed to:
receive an electrophysiologic measurement from each of the first electrode, the second electrode, and the third electrode, wherein a first electrophysiological measurement from the first electrode corresponds to an electrophysiological signal indicative of the gesture being performed by the user, a second electrophysiological measurement from the second electrode corresponds to a baseline electrophysiological signal, and a third electrophysiological measurement from the third electrode corresponds to a common mode signal,
determine the gesture being performed by the user based on (i) a comparison of the electrophysiological signal indicative of the gesture to the baseline electrophysiological signal and the common mode signal and (ii) the movement data from the gestural sensor, and
transmit the determined gesture to an external device for control thereof.
