Great item. Comes with speak to talk button that can be secured on the handle bars. Makes it easy to talk while driving.The VOX also works, but found that even with the sensor adjuments feature, either the wind/noise could trigger the VOX, or you had to yell in order to activate. Unable to adjust sensor to a happy medium.Even with this, it is a great item and would recommend to others.
