I have an X1 and the range is pretty good. The VOX is useless, though. Anything over 45-50mph and the damn thing goes off by itself. Not sure about the high speed mic. Mine is an older version. Maybe the newer ones have better mics.
The best setup was when I used the PTT(push to talk) button. That eliminated false activation of the microphone. Only thing was that it was a pain to attach the button to the bars and then snake the cable up the sleeve of my jacket and then plug it into the Chatterbox.
You would think with today's technology, they could make a wireless remote using IR or Bluetooth in order to activate headset.
BTW, I second the earphones being bulky and uncomfortable and the little velcro pieces they supplied to keep them in place? Ga bage! Some helmets (I'm guessing HJC?) do have little pockets to place the earphones in making them much more comfy but in the Shoei RF900 I was using it in, there was no such pockets. So the pads were out in the open and were pushed right into your ears. They would also move around way too easy and you'd have to adjust them by wedging your one finger in between your helmet and your ear to adjust the earpiece. PITA.
Now they sit around collecting dust. Great idea, poor execution IMO.
