I had this mic now since the day on which it arrived is used on my computer and had ever since from time to time a kind of ground loop in an interview. At first I thought it would connect my device (PC on the same socket as the plant), but just when umstöpseln has finally realized that this was clearly caused by the connection of this Microphones on the socket.
I can only advise against any of this thing, prefer to buy a decent headset for use when making calls.
