AndyUCLEAR - That review at WBB thusfar simply states they like the clarity of the system at a stand still with various levels of road noise. They did not, as yet, road test it as they have all their other units. They also go on to say that sound is 'on par' with other high end units they tested (Sena, Scala, Interphone). I will say they seem to give you the edge whe it comes to 'vocal' clarity, but again this was not during road testing at various speeds. They also say in other reviews that your range is the lowest since you do not incorporate an external antenna. SO, I am still not convinced - especially at $200 apiece.
kuri77 - The only choice for earbuds currently is the Sena model.
