ZUnit an Encyclopedia could be written on your question which is basically all about sound so I'll try to help with this Link.

I use 2 types of Mics (Condenser and Dynamic type) and one of the leading Company's has a decent write up here

You can get good information on microphones for voice recognition on the Dragon Naturally Speaking forums here.

Desktop microphones are frowned upon for voice recognition while a good headset is preferred. However I personally use a desktop mic because I have some breathing problems that headsets pick up as words since the mic is right by my mouth. This screws up surfing the web by voice so I have a Logitech USB desktop mic and it works great for my purposes (I don't do dictation though, just surfing).

I dont wish to know all technical details and history of mics cant this be described in 2 words? Ok basically i only wanted to know what is Sensitivity (dB).

Here is list of mics i found so far,
Labtec, Desk Mic 534
Plantronics, .Audio 15
Cyber Acoustics, CVL-1066
Micro Innovations, Micro Boom
Koss, M18 Communication
Logitech, Desktop Microphone
Logitech, USB Desktop Microphone

Is there much difference in USB (digital) and analog mic in terms of quality?

Btw Logitech, Desktop Microphone and Lobtec, Desk Mic 534 are same? I dont get it, but when i emailed logitech and lobtec they both answered word for word

Please note that Logitec Desktop Microphone is not the same as Labtec Desk Mic 534. They are entirely different products with a few similarities.

I dont think its just coincidence that they look same way and have same spec.

I've had a Shure HW505 for a few years and LOVE it. I think it has been discontinued, however.

Well but from listed above should i get? I think to go with Logitech, USB Desktop Microphone because my pc have alot of noise (cooler ~45 DB) so maybe i need digital mic because i heard it can filter line noise or what is line noise?
Or then Cyber Acoustics, CVL-1066 if i go for analog mic.
