I had a headset mic that worked fine as long as I plugged it directly in to my laptop. Then one day I plugged it in to the port on my laptop's dock, instead of the plug on the laptop itself. In the dock's port it was suddenly so sensitive that it was picking up the slightest sound out of the headphones (and immediately feeding back)! And a conversation going on in the neighboring conference room, that I couldn't even hear on my own! Unless you really focused on something it was just insane loud background noise. But, it was fine once I turned the mic volume down to like 2%. But also, my words could be made out even with the insane sensitivity--I guess that's pretty impressive dynamic range. So: 1. If you're picking up things on the mic you think you shouldn't, try turning down the mic's volume, it might be that your voice stays loud enough, but everything else drops off. 2. If you're getting background noise now, it might not be your new setting, it might be your computer hardware. If you're using different computing hardware maybe you need to fuss with the volume even though it's the same headset as before.
