The present invention relates to an in-ear stimulation system comprising a first device configured to be worn at least partially in a first ear canal of a subject and a second device configured to be worn at least partially in a second ear canal of the subject; wherein each of the first device and the second device comprises: − at least one in-ear active electrode (11,21) configured to receive a bio-signal and at least one in-ear reference electrode (12, 22) configured to receive a bio-signal; − at least one stimulation device (13, 23) configured for emitting at least one electrical or sensory stimulus; and − an electronic system configured to detect at least one bio-signal pattern from the bio-signals measured from the electrodes.
