CK100pro is both brighter, detailed and transparent than the TF10 (and I can safely say the same applies to UE900) but I think it might be too detailed, transparent and bright.
In terms of detail it is the most detailed IEM I had, ( I own ER4S, ACS T15, XBA-4 and had the TF10). CK100pro is analytical and it has nice PRaT. However it can sound bright depending on your source and recording. Meaning you have be selective on what you want to listen to when you are using the CK100pro.
That's great to know. Thanks audionewbi! I've always craved for more detail in my music and the CK100pro seems perfect for that. I have no problems with it being bright, if it gets too bright I can EQ down the treble.
By the way, does it sound good out of a Clip+ or Clip Zip? I will mostly be using it with my Zip.
