Mod Mic 4.0 Doesnt sound very good :(

So I got my Mod Mic 4.0 the other day, and it sounds really bad theres lots of noise and echoing in the background and everyone says they can here my mouse clicking and me tapping on my keyboard even if i do it lightly :( 

So if anyone would like to tell me why it sounds bad or anything troubleshooting tips i would greatly appreciate it :( 

Turn the volume of it down in windows it sounds like it may be to sensitive and picking up a lot of background noise.  Go to control panel, sound, then recording and do the properties for the mic and change the level of the input.
