People have been using two out of laziness since a shield is not absolutely necessary for function. Looking at the pins point-on, from left to right, they're mic+, mic- and shield. I strongly recommend you use shielded wire, though soldering the shield to pin3 isn't especially critical (attaching it on the MULF side is).
