Wanted an improvement over my onboard laptop mess.   No interference, hiss (from 32ohm), very quick connection, good volume.   Bass reproduction on EQ Bass1 is spot on with my AKG K550.  Stereo seperation seems spot on and the general tone is much more appealing through the E7 in comparison to onboard laptop sound.   The bass and quality of sound is the most promonent improvement over laptop on board sound.

My last set of cans have all been Sennheiser's, (except a pair of Shure SRH550's which were very thin and uncomfortable).   Sennheiser Momentum's were top of my list next to the HD598's.   My music tastes are very vast, but commercial, varying from Boyz II Men, Bruno Mars, to Bon Jovi, Kings of Leon, to Biggie and Jay Z.   My normal listening kit are Monitor Audio speakers, Quad L sub and Yamaha amplification, which has a very good sound-stage, outstanding clarity with very deep musical undistorted bass.  This is what I was looking for in...
