Updated review:
I have burned my original pair in for about 40-50 hours and they have really smoothed out in the upper end. These things definitely are NOT good for trance/house/electronic IMO. EQing them to try to get good bass response results in major distortion in the bass.
They are still mid-forward, but with EQing, they now sound better then my other (cheapie) IEMs for other music I listen to (Queensryche, Eric Clapton, the Eagles, etc.). The shrill highs are gone! I have a pair for my wife and she listens to Country and pop, and they sound good for that (EQed). The bass is OK when EQed for non-bass heavy music.
They are not the most comfortable (the V-Moda bass freq is the most comfortable I own, I think because it has a longer stem). All-in-all, not bad with a BOGO deal.
