Could you connect the unbalanced output of the electret module to a small audio transformer (LT700 sort of thing) and then use the secondary winding to provide your true balanced output, maybe with the centre tap earthed? Not sure about audio quality though. You may need to play about with equalisation depending on your requirements.
