Comparing the HE-400 to the K702, the HE-400 is more ragged with higher peaks and dips and a fairly similar curve. The D2K have a bit less treble, but still rather close save a bump in the midrange. The DT880 have less of a bump at 2K, but a larger peak at 10K. The 598 removes the 2K bump while retaining a similar FR again. I don't see how you can find the Q701 "bright" compared to these honestly - it's a pretty flat phone overall.
