How is the PK2 like compared to shure E4? I have been little disappointed to E4's flat sound. Sometimes it's great but in rock it's often lacking a lot. Even with Vivaldi's concertos sr60 reveal much more detail in the background, cloths moving, breathing. And when there is compelete silence with E4, with sr60's I can hear something.
It just annoys me that I would have to switch from E4<->sr60 depending on the album for best results at hand, and of course, on trips I have only E4's with me. EQ doesn't seem to solve this problem either.
I'm thinking if selling E4 and buying PK2 would be an improvement for me or should I stick with E4? I find the E4's unpleasant if used for longer periods of time ( as sr60's, they both make my head warm somehow). I don't have an amp and my source is meizu m6. I would use PK2's as portable solution, I might get amplifier and speakers soon for home use.
PS: Isolation is nice but most of the time I listen at home or at situations where complete isolation isn't necessary ( but not harmful ). I'm open for other suggestions too.
