I have 2 planar IEMs but never had BA. I hear explanations of Bass mids and highs when they keep comparing to dynamics, but it all sounds like planars and BA are similar? Bass is tighter and accurate, but not as impactful, mids and treble can be very well reflected with them.

So, anyone who has single BA (Etymotic sr4, Aful Magic One and the likes etc.) and single planar (letshuoers, Tinhifi etc.), please tell me your experience.
