Good review and very consistent with what I hear:metallic bright, slightly boosted upper bass (perhaps to balance the highs?), but fun. It's possible these were tuned to sound exciting when fed by the typically bland output of a cell phone; a headphone tuner could work some magic here.
Switching between these and my Utopias using a CEC T53Z cd player as a source feeding a COS Engineering H1 and I keep thinking "Not exactly accurate, but not nearly as bad as some early reviews would have one believe." The brightness initially can be piercing on some material, but does diminish a bit with use. Nevertheless I think most of that is the ear adjusting to the signature. I would not pair with a lean/bright amp, source or material!
Pair it with a sweet sounding system and these can be enjoyable. Well recorded music is served well once the ear adjusts.
Very difficult to find, but the poor market acceptance means I was able to get them at a steal (low 3 figures) from a store in the UK to use as in a portable setup with my Questyle QPR2.
