I think that the SQ of the U10/Q10 is really good...
The EQs of my U10 are well set BUT the user EQ is unuseable (sounds really muffled)
The Screen and the UI are very good.
Before an upgrade to the S:Flo2 I am going to try other iems (Hippo VB).
I'll give my impressions and compare them to the re0 coupled to the U10.
