Just got myself a Scala Rider (mainly for hearing the voice guidance on my sat nav rather than actually answering calls) and would like to say this works amazing well. Would recommend to anyone looking at getting a bluetooth headset for their bike. Tested with my wife yesterday and it works well for phone calls. She asked me if I had stopped (when I was riding 80km/h) when I chatted to her because it was so clear. Speaker quality is decent, fit with the helmet (full face in my case) is brilliant and the design is really good. Voice quality for outgoing is brilliant (according to my wife) P.s. You can pick them up cheaply on ebay so shop around if you intend getting one.
