The polar pattern of the cartridge is indicated by the model number suffix:

C = Cardioid, S = Supercardioid, O= Omnidirectional

MX391: Includes an attached 4 meter (12 ft) cable terminated with a 4-pin mini connector and a separate preamplifier. A rubber strain relief is provided for applications where you want to remove the 4-pin mini connector and connect the microphone cable directly to screw terminals in the preamplifier.
