Looking back at my point it does seem a bit emotionally driven... To explain, I personally prefer a cleaner headphone with a revealing and intimate sound signature. However seeing at what the genres that will be listened to; the Mixrs are an OK shout. I just feel that comparing the two, the M50s outclass the mixrs in most areas, and technically presents music much better. However the mixrs make up some ground up utilising a more carefree, shameless and fun sound sig.
I guess its down to preference, if I had to choose I would definitely not pick the Mixrs, for the whole package there are plenty of other brands (m50s included) that give more bang for the buck
