You forgot about the headphones! I have been rawking the same M50x's since 2014.
I still use a pair of the old M50s daily that I bought around Christmas 2010. And it's not like I've taken that great care of them. Absolute troopers. Though they are starting to show their age now. All the covering on the headband has fallen off and I recently broke a little bit of plastic which ensures the cup stays in place when up against the resistance of your head. I had to tape that up so now left side no longer folds. I guess I dropped them one too many times. I'll probably try to get another 6-12 months out of them.
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.
