FitEar IMarge Universal LP W2 Ultra we have the responsibility to"1 plus 1" configuration that makes the most of the full range unit FitEar IMarge uses a "1+1" configuration that slightly reinforces the high frequencies in the full range unit, which was developed through the development of FitEar's hybrid models.
