Well I'm a beginner at this so my ranking could be very distorted. 
My main type of music is Trance/House/Progressive because I think what music you like also affects how the IEMs sound. 
I'm also more of a bass fan.

I hated the those Hifimans, though it could have just been that I didn't have a good seal with them, so my impressions are a bit off.

How are the superdarts? Those looks really interesting.
