Exceptional treble with solid bass. Great techs. Some may find the midrange a bit clinical. Fit will be a dealbreaker to some. Cons: Poor fit.

Top tier clarity and great technicalities, other than a hint of BA timbre plasticness to it. Mid-bass recession is the con in the tuning, turning it into a dry IEM. Top performer nonetheless.
