I prefer the Shure SRH 940 by a long shot to the K701 and, by extension, to the SRH840 and certainly the K550. It is astoundingly very linear with a hair of excitement of 1 to 2 decibels of treble in the 8 to 14 kHz range and a slight dip in the lower bass by 3-4 decibels starting from 50 Hz to 20 Hz. Unless you are bass fiend or preferences lie with an artistically warm sound, these are some of the best headphones under $1000. Bear in mind that this assessment was made over years with countless Beyerdynamic, Grado, Sennheiser and even HiFiMAN headphones I have either bought or used for hours each on an individual and head-to-head comparison basis.
