I currently own the DT1770 and I kind of regret it. That headphone sounds very dark with no fine detail to the sound and the treble then jumps up. The DT1990 was just a bit better but nothing stands out when I tried it at RMAF. Before I ordered the Elex. I tried the V3 of HE560 since I like the original version two years back. But the version I got was distorting in the mid-range and other QC issues. I return it. I enjoy my HE-400 far better and it has much more pronounce bass and clear in the details. I was concerned that I might hear the Elex metallic coloration but that was not the case. The Focal Elex is outstanding for vocals. Male vocals and chorus are the best and natural sounding I ever head on a headphone. Very smooth and very detailed. The Elex was being driven by Monoprice Liquid Platinum. I could not hear any harshness or edginess on the treble. A real keeper for me.
