After opening the folds, I have not tried the proper functioning of the microphone, but I tried it plugged into the camera with her little jack cord; the problem is that I use as a feeding flu, whose cable is also connected to my Nikon camera, despite that these are two different outputs (one upstairs and one downstairs), 2 wirings do not connect simultaneously because they touch; so either it is or it is one or the other. For my use, connecting the two wirings are indispensable to me. Would recommend for those who do not use the power flu with their camera.
