Have just replaced my Shoei which was 6 years old for a Nolan N104 flip up. Also installed the n-com B5L system and was surprised how clear it is. I've used Scala before but this system is much more sophisticated. As well as linking 6 bikes (not necessarily using n-com) it has call conferencing as well as phone and GPS, FM RDS radio which is very clear even with lid up. Fitting is very discreet and compact, only downside is trying to remember the button sequences for each part of the system. The helmet is a nice fit with good vision and hopefully will last just as long as the Shoei.
