I like full face but am claustrophobic so I need a modular so I can flip it up every once in a while. I have a Shoei Multitec now with autocom speakers installed. They fit fine, but only problem with this helmet is the liner is not removable. It is the best helmet I have owned.
Before the Shoei I had a KBC FFR. Speakers fit fine in it but the flip up mechanism was pretty flimsy.
I second the multitech if you want to consider modular.
