Microphone uses 3.5mm and speakers use RCA - why shouldn't you be able to connect both at once?

It might be worth pointing out that if you plan to use a headset and speakers at the same time you need to manually unplug the headset if you want to switch back to the speakers. One of the little quirks of the titanium HD.
If its just a stand alone microphone and a set of speakers then there's no issue.
