Sennheiser HD 380 Pro VS Audio Technica ATH M50x

I'm a bit of a headphone enthusiast, and I've posted a lot of headphone related content recently.  Well, in some of those videos I was asked about the Audio Technica ATH m50x.  

I've never used Audio Technica anything, really, expect for the needle on my Crosley turntable, but that doesn't apply. 

Well, I picked up a pair of ATH M50X from Amazon Prime with one day shipping and boom!  Here we are. 

You have to watch the video to find out what I thought.
