I could foresee the K702, the Q701 and K702 Anniversary Edition test, the K712 Pro is superior in my opinion, all three: the Q702 has the usual stage, but is the weakest in the lower midrange and the bass, which is already better Q701 in the middle, but it still lacks a little bass. The Anniversary Edition is very good, right here the bass, probably through the gel apple earbuds, but I could see the difference in price to K712 Pro but then not answer.
The K712 Pro now sounds even better to what I now find reasonable price and the comfort is also good.
All potential buyers I would recommend headphones warmly. A small drawback is that the newer models of K712 Pro no longer "Made in Austria" appear to be.
