It's one of the more annoying issues I've come across since getting into this hobby. All of the various interpretations of descriptions. There is no rule book for them. And because of that, responses become emotional whether they are meant to be or not. Some one calls something flat sounding. Someone else takes umbrage to that, taking it personally because they love that equipment. Personally, I find the C10 to be flat sounding, and because of that I would refer to them as being more neutral in comparison to other "fun" sounding sets of iems. I don't say it to offend, or to combat others opinions. It's just how I feel about them. I also don't think they sound bad per se. Just not my cup of tea. Kind of like how I feel about the HD650. A little too boring for my liking. Emphasis on MY. Y'all may love it or hate it accordingly.
