A personal entertainment system calibrated and controlled by the biological or physiological condition of a user is disclosed. The entertainment system includes a media player; a sensor operative to detect biological parameters and generating a control signal in response to the detected parameters, the sensor being operably coupled to the media player; and a processing element which associates the control signal to at least one type of media preference, and causes the media player to provide media stimuli based on the control signal. Thus the media stimuli provided by the entertainment system is specific to the individual preferences and detected condition of the user.
