this particular model has vents in the ear pocket for cheek pad ventilation. you can see the pocket, and holes like a colander for this venting in the shoei cutaway picture.
duhastme, shoei has adjustable cheek pads but, you have to replace the whole cheek pad to get the adjustment (thicker or thinner). if shoei made thicker/thinner ear pockets and sold them separately, or they came with the helmet, I could see your theory on the pads at the ear area but, in this case, it appears the cut out is for ventilation and speakers.
thanks to all that helped, now I have to come up with the budget to buy it. LOL! Ski
