Hello,
I have a gt air and we manage to clip the earphones in the hollow of the ears, it's quite comfortable. I've got a gt air and I'm able to put the earphones in the ear cup, it's quite comfortable. New installation also worries, to pass the cables under the foams and all and all.
I don't know about the shoei notes.
A+
So we have talked up to 100-120km/h without any problems between 2 drivers and it felt like talking normally live with each other. I don't know about that, but I assume that if the quality doesn't decrease significantly up to 120km/h, we will still understand each other.
With a lot of faff and retrofitting a helmet which you'd be willing to cut up to make space for the ear pieces, yes it could maybe function.
Sena cycling helmets with in built intercoms might be a better solution. I have not personally tried them but do look it up.
