Great choices, I’m glad to see only one chose Beats by Dr. Dre (someone who happened to work on them). 
The Audio-Technica ATH-M50x seems to be a good choice.
I still love my 7506’s even though they are now being held together by electrical tape. They are made using 20-year old technology so the labels are peeling off and earpad covers are wearing off. I just saw you can get a good deal on them on Groupon.
