Razer Tresher Ultimate 7.1 uber sensitive microphone

So I bought the headset a week ago, and I love it! It has significantly improved my comfort while gaming! But.. the microphone.. it picks up the subtle grunts of a fly in the next room defecating, which can make skype calls etc.. problematic when it picks up whatever decides to make a sound. There doesn't seem to be a satisfying way to adjust sensitivity, unless someone knows? Synapse doesn't seem to support it, which seems odd for such an expensive headset. I am at a bit of a loss, because apart from this, which is gradually driving my gf insane, it is an excellent piece of hardware!
