Yes, it seems a little less prominent, but at least on my side it is still quite present. It seems to be dependent from the actual signal coming from the microphone, if there is not any signal coming in it's barely present; as soon as you start speaking, it scales accordingly.

Luckily i've an old USB to dual jack adapter laying around, but it's not an ideal solution for me.
