I'm not going to review this,so just put honest comment here.
 
 
Comfort is decent, Isolation is so that I can't hear my mother yell, Light bass but punchy and tight ... I don't care about bass so just put it as that ,
Detail and soundstage is decent for a price (I except a big upgrade from SHE3590 and RE400 but for IEM I guess it can't be as Dramatically as Speaker or Headphone),
Natural sound treble wise, not so Analytical as monitor headphone thought.
 
 
But what stand out the most is Vocal, especially Female Vocal! Female vocal tonality is so beautiful so that I take a big smile when I'm listening to my JPop Singer track,
I dare you to say which IEM can do vocal as beautiful as this, it even put RE400 to shame!
Oh and male vocal are quiet handsome too (but more gay-lish thought)
 
Just beware that treble can sound harsh with high impedance output thought.
 
Out of Ipod Classic is sound queit good
Out of AK100ii is sound Excellent Good
Out of Dpx1 Balanced out is sound I hope that I know it! (someday)
 
 
You can find many IEM that has better SQ than this, But for female vocal This is the Unbeatable Queen!
