The invention relates to a headset apparatus for detecting a multi bio-signal comprising: a headset body configured to be mounted on a user's head; a plurality of electrodes which are exposed on an outer surface of the headset body so as to be in contact with a forehead of a user when the headset body is mounted on a user's head; a brainwave detection unit which is embedded in the headset body and which detects a brainwave signal based on a signal detected by the plurality of electrodes; a heartbeat detection module which extends from the headset body through a signal cable and which is configured to be mounted on a user's ear to detect a heartbeat signal; and a headset controller to determine a complex stress index based on the brainwave signal detected by the brainwave detection unit and the heartbeat signal detected by the heartbeat detection module. Accordingly, the apparatus can measure a user's stress index accurately by measuring a multi bio-signal such as a brainwave and can be manufactured in the form of a wearable device.
