Helmet to helmet

I also have the Sena 20s. It works very well. I have in a Scorpion full face and unless I'm riding into a headwind, I have no issues hearing on it. I find the prompt voice to be a little quiet when issuing commands but have no problem hearing my wife. The range is pretty good when there's a line of sight. I think they advertise 2km, but that is not true. We have been close to 1km apart before with a good connection but if one of us rounds a bend or goes over a hill, it drops. Defeinitley like it though! I will say it took a few tries to position the speakers just right but once you get it set the way you like it, it sounds great.
