The microphone is supposed to explicitly filter out other noises such as "closing noises of doors/windows, keystrokes, mouse clicks etc.".
If you are using a Windows PC, you can click on Sound System Control under System/Sound in the top right-hand corner and a sound window will pop up.
In this window you go to Recording and select your microphone by right-clicking on Properties.
Under the tab Level you can set your microphone to 100 so that others can hear you louder.
Under the tab Advanced you should set the standard format to 1 channel, 16bit and 48000Hz. (This is the most sensitive)
The microphone has been working for me for more than 3 years now without any problems.
