I have to agree. I didn’t realize how much comfort affected my perception of iems, but the ie600s “disappear” so I can concentrate on the music and not be aware of “something in my ear” distraction.
I generally don’t like moldable hooks, as they are too stiff, but these are flexible and comfy
This is also my experience. This is an iem that i reach for instinctively, although I have a TOTL iem available. I guess the combination of comfort and reasonable sound quality is the reason.
I really appreciated your review, as it mirrors my experience. When I first tried the ie600s the bass was overwhelming. I did tame the bass with EQ to get there. In my mind, these IEMs punch above their price with a bit of parametric EQ.
