Bit more observations while in the thick of things. How much bass do they guys have, well I did mention previously that I’m a speaker guy, right, (not solely though ) so I do compare my phones output periodically to them. Doing just that while listening to Underworld’s dubnobasswithmyheadman the K712s had more apparent bass than my Dynaudio Special 25s which are augmented with a 15” Velodyne, and it’s dialed in rather flat using Velodyne's SMS-1. I’d really have to say that the K712s may have too much of a good thing, the Senns HD700s are much flatter and match the speakers/sub output to a T, but without taking an actual reading I would venture to say the AKGs may have a bit of a mid bass bloat. The HD700s also match my Dynaudio 25s tonally, again the 712s coming across warmer and less defined, the HD700s having better image focus and staging, which I attribute to the Sennheiser’s attention given to designing and integrating the new ear cups, baffle and driver. Still the K712s are an enjoyable listen and a far cry from my original K501s and K701s and if I hold onto them, probably my go to for movies.
