An exemplary evoked response measurement system includes a sound processor external to a patient and configured to direct a cochlear implant implanted within the patient to apply electrical stimulation to the patient. The measurement system also includes a headpiece configured to connect to the sound processor by way of a cable, affix to an external surface of a head of the patient, and facilitate wireless communication between the sound processor and the cochlear implant. The measurement system also includes a plurality of conductive contacts communicatively coupled to the sound processor and affixed to the external surface of the head of the patient to detect a signal representative of an evoked response generated by a brain of the patient in response to the electrical stimulation. At least one conductive contact is physically coupled to the headpiece and located between the headpiece and the external surface of the head of the patient.
