Interesting comments here regarding the NH and Mojo combo. Sounds like some people are really enjoying it. I am planning to pick up a Mojo here probably in the next few weeks. I'm hoping it will sound somewhat close in performance to the 600i, cause this thing sounds good, aside from the issue I appear to be having with occasional ticks and pops during playback. I can tell that the NH really use take advantage of the power.
I have been going back and forth here between the Elear and the NH using my dad's Questyle 600i, and they are just completely different headphones. Most people would call the Elear "warm", and in a way they are warm, but they don't really flesh out the midrange how I like. It seems I spend more time being impressed with the sound than I do enjoying the music. Switching back to the NH, there is an immediate feeling of "oh wow there is less detail", but the sound is much more intimate and personal. Things sound closer. The midrange is much more dense and harmonic.
