A:AnswerIf your monitor has the standard audio jack then these will work. More than likely unless your computer is an all in one, your audio output is on your computer and not the monitor.
A:AnswerI think so bc there is a port for headphones so that should be the same. If your microphone plug fits in the standard port then it probably works
A:AnswerSorry, I am not sure I understand what kind of setup you have and if I am qualified to answer the question. I am not sure how your transformer works and what you mean by a push pin. Without seeing a picture of your unit I can honestly say if these would work for you.
A:AnswerI am very pleased with these speakers. The sound is clear (highs and lows) and I am completely satisfied with my purchase. Logitech never lets me down...
