Compatible mic?

What PC do you have?   Always include your PC model/number on any initial problem post.

However, in general if you have a mic jack on the front, a standard "Computer Mic" is all that's needed.  Do not use the combination cell phone type mics as they are mostly incompatible and cause problems on a PC.

USB connected mics will work too.  Just depends on which you want. 

Regular P.A. system mic's will not work.  You need one designed for a PC.

Here is an example of a standard analog computer mic:

Here is an example of a USB mic

its a xps 8900 on a windows 64 bits system..of the 2 mic you suggested which is better for my purpose?

Either one will work for speech.  The analog model will save a USB port, if the USB ports are needed.  I would go with the analog model, which keeps the USB ports open for other uses.  But either will do the job.

thanks
