Headphoneus Supremus
Because I adore them, so for me, subjectively, it is true. I have spent years looking for their SQ and I didn't think it existed so I'm very happy.
Well it seems that i've been looking for the balanced, controlled, extended detailed, lush sound of the 660S without zero harshness in the treble region, the most accurate bass i've heard. ( I think some people confuse what bass is ?? ) The mid range is wonderful, vocals you can get lost in.
Most of my equipment is Sony, so i'm not knocking them, just giving an honest assessment of both.
