HS70 Modmic 5?

Hey, I'm getting an HS70 in the mail soon and I was wondering if replacing the included microphone with a Modmic 5 is a good idea. From watching videos it's clear that the included mic is a bit lacking, but I'm wondering how much of that is due to the microphone itself and how much is the wireless aspect of the headset. If it's the former then maybe I can get a significant mic upgrade later down the road without sacrificing the wireless functionality of the headset. Thoughts?
