I considered the 712, but the I heard they lose a little bit of detail due to the freq curve having more bass. Others have said EQ'ing the 702 can emulate the 712 if thats what youre going for. Ultimately it was because I got the 702's for a steal, but! Subjectively, I love concerts so the HUGE (some say unnatural) soundstage these provide are second to the 800s. Currently I have them running off the schiit magni/modi stack with peace EQ harman curve but to my preference and theres just something with the way they sound that others headphones dont reproduce. Ive tried the 560S, hd600, sundara, cheaper headphones like the sph9500, pc38x, m50x and koss kph30i's and I sold most of them because I kept grabbing the 702's.
