Thought to write this Jergpad story here: Several months ago I purchased the HE400's, and while clearly a step up in terms of perfomance, several things bothered me about them. They were unforgiving of less than stellar recordings and the presentation didn't seem very natural. So I ended up purchasing the HD650's- so forgiving and natural sounding. But they're slow- I missed the fast decay of the HE400's. Enter Modulor's Jergpads. Now the HE400's sound almost as natural as the HD650's, and the treble spike which caused earlier discomfort is much less pronounced. I now reach for the HE400's- they're more detailed, they're quicker- with Jergpads they're a superior headphone than the HD650's. Honestly the treble spike really turned me off for awhile. And if the recording is very sub par, the HD650's make virtually any recording listenable. Jergpads helped to demonstrate how great HE400's can be, and am considering one day HE500- if my wallet can handle it, and it's not too heavy. TL;DR
Jergpads are the saving grace of the HE400.
