This is the truth. I have both. The m50x sounds great for it's price point. But in comparison to the hp50 it sounds like an amateur headphone (bass isn't as tight, more closed in, midrange is flat and more recessed). One thing, the hp50 amped with the fiio e12 with bass boost on (for some songs, not all) gets an 8 in my book. Just amping it gives it at least a point more IMO.
