Bartman,
Can you post a photo of the inside of your helmet? Can you tell if they did and cutting to get the speakers to fit?
Thanks
Ed
It doesn't look like they did any cutting, although it does seem they put a little padding behind the speaker to bring it out a little on the right side.
I will tell you this. The standard boom that comes with the 584's is too short so they substitute a longer boom so it come directly in front of your mouth.
Here are the images from the right side.
With the cheek pad removed:

Hope this helps.
