I received my E12 2 days ago. It must be a newer version I think as the bass boost switch seems to really thicken the sound. It does not sound to my ears like a subtle change. I'm sure many would really enjoy what the bass boost on this newer version does, however it is not what I want to complement my specific set of headphones. Would anyone be interested in trading their v1 for my newer model? I feel that the v1 may be more of what I am looking for in terms of an added bass boost.
The Bass Boost on my E12 is a true smooth transition on my HD600.......no affect or whatsoever in other areas than bass.
