1. A physiological measurement device configured for placement at an ear of a user, the physiological measurement device comprising:
a body portion;
an extension portion connected to and extending transverse with respect to the body portion, the extension portion configured to be positioned at least partially in an ear canal of the user's ear when the physiological measurement device is in use, wherein, when the extension portion is positioned at least partially in the ear canal of the user's ear, the body portion is positioned outside of the ear canal and adjacent tissue of a concha of the user's ear; and
at least one light emitter and at least one detector, the at least one light emitter and the at least one detector arranged in a reflective measurement configuration on the body portion of the physiological measurement device, wherein the at least one light emitter is configured to emit light towards said tissue of said concha of the user's ear when the physiological measurement device is in use, and wherein the at least one light detector is configured to output at least one signal responsive to detecting at least a portion of the emitted light after reflection from at least a portion of said tissue of said concha of the user's ear when the physiological measurement device is in use, said at least one signal indicative of at least one physiological parameter of the user.
