which microphone has sensitive input?

Hello,
I need microphone that catches every sound, like you are clicking the mouse and it actually catches that.

I used to have one like that but I lost it and it wasn't mine so I don't even know what brand it was..

but it's really cheap, nothing fancy, I am just sick of using headset and it has weak sound input no matter how close I try to speak to it.

thing is I don't know which microphones are like that and they also have measure "DB" which I am not familiar with..

reason I want this is because I hate to turn on Mic boost from Windows because they make noises on the background after recording it. I didn't need Mic boost before when I had that mic.

I am looking for the mic that has stance like this one
