Mine literally broke last night. Proof of karma for not mentioning them in my original post. Fixed it with duct tape. 2 years of the best budget studio quality and I treat it like I treat my combat boots. One day I'll have a pair of AKGs. One day :')
I got mine from Massdrop, so when a buddy of mine wanted good headphones I convinced him to go for the Massdrop sale then, the AKG K7XX. In a side by side comparison I kinda love mine more. The M50x is much more 'precise', if that makes sense. It's like it comes with a mixer built in or something, whereas that AKG sounded like it had some drowned out sounds.
That's good to know. But AKG has enough high-end equipment that I'm sure there will be something to top the M50x. That said, again, the M50x is pretty freakin' amazing.
