I need a decent pair of headphones. Source will just be Spotify on high quality. Music is very eclectic from classical/instrumentals to things like Girl Talk and Hood Internet.
 
Needs to be closed so that I don't annoy people around me. 
 
It will be powered from a Macbook Retina 15, latest version. I could up to a headphone or USB DAC or amp or something but I don't want to spend much more than $100. Any suggestions? 
 
I was looking at the ATH-M40x but I've been told the soundstage is not great.

The Audio Technica ATH-M50 can be had for $125 on Amazon - as long as you don't need the detachable cable that the newer M50x has, it is a heck of a deal.
