1. A wearable audio product for obtaining biologically-relevant information associated with a user comprising:

  • a first electrode placed over the user'"'"'s auditory cortex on a first side of the user'"'"'s body;

    a second electrode placed on the first side of the user'"'"'s body;

    a first reference electrode placed on the first side of the user'"'"'s body;

    a third electrode placed over the user'"'"'s auditory cortex on a second side of the user'"'"'s body;

    a fourth electrode placed on the second side of the user'"'"'s body; and

    a second reference electrode placed on the second side of the user'"'"'s body, a processor coupled to the first, second, first reference electrode, third, fourth, and second reference electrode, the processor configured to take one or more actions based on signals received from the first, second, first reference electrodes, third, fourth, and second reference electrode,wherein taking the one or more actions comprises;

    combining signals from first side movement artifacts, the user'"'"'s brain, and the first reference electrode to generate a combined first side signal;

    combining signals from second side movement artifacts, the user'"'"'s brain signal, and the second reference electrode to generate a combined second side signal;

    comparing the combined first side signal and the combined second side signal to output a difference for the first side and a difference for the second side;

    applying a first closed feedback loop for signals received from the first side of the body including the difference for the first side signal, applying a second closed feedback loop for signals received from the second side of the body including the difference for the second side signal, and removing noise from the received signals based on the first and second closed feedback loops, wherein removing the noise comprises cross-correlating the signals received from the first side of the body with the signals received from the second side of the body; and

    an electroacoustic transducer coupled to the processor.
