Thanks for the feedback on my other and first thread yesterday.  New to high end audio from a headphone perspective.
 
I don't have any close places to try audiophile grade products but think I narrowed the portable amp/closed headphone to the set listed above.
 
Any feedback or other recommendations of combinations that work well.
 
Use will be mostly travel, on planes so need closed headphones.  Now using IE8 direct into an iPhone 6 with custom ACS inserts with good sound isolation but prefer over the ear as easy on/off.
