I bought this Superlux EVo, and this is my initial reviews:
Soundstage is spacious, wide, and precise enough. This is the first strength. If you hear 3d or binaural recording, it is so real.
Bass is the other strength. Low and good. Sub bass rumbling but not boomy. In fact I like to use this when playing bass-drum-heavy music such as Royals by Lorde and songs by Fifth Harmony. Bass and beats music sounds wonderful.
Mids are weaker compared to my Sennheiser HD598 or perhaps Grado. Detail is present, but not enough presence. Perhaps, yes it is true, the mid bass slightly influence this area. This is not for accoustics. I do not recommend this for jazz also, because of weaker mids. I am a jazz lover, but this is not for it.
Treble are average. And I am not impressed in this area. No sparkling crisp, but rather standard trebles.
It is comfortable. Big, and round. More comfortable than Audio technica M40x I have.
Can I train this headphone? I will try.
