[X-Men] How is Magneto's helmet supposed to work?

Can't Charles (or any other telepath) "enter" his mind via the front? Or from the spine for that matter?

It's a Faraday cage. However telepathy works, it acts like lightning and instead of getting to directly contact the mind, the effects are blocked by bouncing around the outsides of the helmet. Same for foil hat wearers, and the Juggernaut bitch.
