Where is a headphone/mic jack?

I was looking at the specs of the speakers I am going to buy, and it said that it didn't have a headphone/mic jack. Are they usually supposed to be on speakers, or on the monitor, or on the motherboard with the speaker jacks?

Thanks

(and please will someone look at the topic about the typhoon mouse/keyboard set - I have some questions that need answering before I buy)

Thanks again

depends on what speakers your after ,5.1 setups may well use up all your connections depending on what soundcard / motherboard u have

a speaker jack is also your headphone jack (the green 1)

and the mic jack is what colour?

Red

I know this is on another thread, but could someone PLEASE realy to the multimedia kit thread - you don't have to own it - some, questions you might know the answer to.

I'd be REALLY happy if someone would reply

Thanks (I mainly want to know about optical wireless mice)
