I can't speak for the Mojo2, but the E3 are capable of doing things with some albums/tracks that I have never experienced before. I am running CD60->BF2/64->MJ3->E3 on balanced cables, and am finding that this setup can take recordings and show you all the little tricks that have been done in the recording studio. I hear vocals and instruments not just panning left and right, but also forward and backward, they even seem to stretch vocals somehow, plus so many other panning and stretching effects. I am also hearing room reverb on vocals and guitars like never before, these special effects really enhance the listening experience. I have listened to my same Frampton Greatest Hits CD for years, today I heard so much more than ever before, not just micro details, but all the special effects done in the studio. The live tracks were really wide and spacious, hard to believe these are closed backs. Also recently got into the blues, Clapton, Muddy Waters, BB King, the guitars on some of these tracks sound so real with great punch, very satisfying. This setup can make previous seemingly average tracks sound like incredible tracks. It's hard to believe that these sounds are locked away in 1's and 0's, but just need a little help coming to life. The Mojo2 might achieve some of this, but I do believe the E3 scale really well. I am now convinced that the E3 are an amazing headphone.
