Can't actually see them yet cause I'm at school but power armor is pretty leniant(sp?) on the size of stuff. There's pictures of the pauldrons coming up to the jawline, middle of the neck, top of the head and about everywhere inbetween. What it comes down to is what looks the coolest to you pretty much. Also if you have them up to your ears mobility becomes an issue. I'm sure you could pull it off with some creativity though. Same issue will come up with the backpacks methinks.
