Well, the HiFiMAN HE-560 arrived a couple of hours ago, and I'm at a crossroads. I'm a basshead at heart, and my M1060 allow me to enjoy an open planar with some real grunt down low, and I was hoping for the same from the HE-560. Unfortunately, while the lows are definitely present in the HiFiMANs, it can't handle my level of bass, lol. The mids are amazing, maybe the best I've ever heard in a headphone, and the highs are crisp and fresh. But the basshead in me just isn't satisfied. Now to the crossroads, do I keep them because they are mint and I got a great deal? Or do I let great headphones go because they don't hit my basshead sweet tooth?
