Ah I see, they are worth trying. The aesthetic differences are quite different between the two. The ear capsules are smaller on the K612 and the plastic is of lower quality compare to the K712, not sure about the Q701, 702, etc on top of my head. Some reason I seriously think there is some metal on the K712, the outer part of the earcups are very hard like metal and sort of cold to the touch. The K712 has sort of a textured and matte finish to them. The headband wires feel textured compared to the K612s smooth headband wires. There are quite a few differences in aesthetics and build between the two. The K712 is very well made and very solid feeling in my hands. They feel better made than my Beyers I had in the past.
