Get that classic vintage Unidyne look with modern sound using the 55SH Series II, which is tailored specifically for vocals with a bright and present high end with a frequency response up to 15kHz. The cardioid polar pattern makes absolutely sure that you're heard, rejecting all of the noise of your surroundings to allow you to cut through the mix without bleed-through.
