Does anyone know if there have been some in-depth comparisons between the K10 and 4C? I'm considering the 4C as a sidekick to my K10s, but only if the differences are significant enough in the direction I'm looking for. (slightly leaner sound and less forward presentation of the mids)
Yesterday I heard the 4u and K10u. If I could not afford the 10 I would probably be very happy with the 4. The 10 just seemed to have a little... more.
I cannot really see why you would want the 4 if you have the 10. Unless you wanted a tool for mastering or something.
Personally I really like the idea of a CIEM that has a carefully selected sound sig. Rather than a neutral sound. It seems to me that the former is where art meets science.
Maybe after I have owned the K10 for a while I too will hanker after a different sound. I kind of hope not. I would like this to be the end of my CIEM journey just as the HD600 is the end of my headphone journey.
