Well, they finally came today. I've had them in for 4 hours now and they do feel nicer. I am not saying these will be any kind of cure for ENS but depending on your symptoms, they may help.
In general, they do cut down the air flow a bit and I'm not sure why they would do this for normal people but for us it is good. Not only does it limit the air intake a little, more importantly, they do seem to make it more comfortable for me to breathe. I think it is indeed the turbulence that they cause by having that cork screw design. Again, I am not sure why they designed this this way for normal people, but for US (ENS) it does seem to help in those 2 ways: 1) adds turbulent flow ( I am too open and have Laminar flow through the nose which is bad)  2) it does limit flow a little.
