I tried the CK10 last night and it honest was an eye opening experience! I have never tried BA iems before and if I were to use one word to describe it, it would be Vivid. It was love at first listen lol. I was under the impression they would be flat and boring but they definitely were not that!
Definitely agree with your first experience. BA drivers are very very different in their response compared with dynamic and CK10 are definitely one of the best implementation of dual knowles drivers. I have tried multiple earphones in the similar and lesser price range - dynamic, single BA, dual BA and for my money CK10 delivers the best sound to fit my requirements. You'll fall in love with their clarity, speed and transparent nature.
