Since this topic has arose from the lost world of topics, figured I update my experience.
Helmet is phenomenal, get it if you have $$. If you don't have $$, save for this one and don't waste on cheap crap and especially buy from Mike!!!
Now, to the specifics. I was gifted a Sena20S for the new year holidays. with some small modification of the SENA (i'd never chop the helmet) I was able to put the speakers into the X-14 ear pockets and cover them with the original pieces that were in there. the only thing I had to change on those small hole cover pieces was to carefully remove the thick foam glued to them and that was enough. If I didn't have the Sena device sticking out on the side of the helmet, you wouldn't even know I had the damn thing. All the wires are nicely tucked away with nothing sticking out.
