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.
Sansa clip+ is more than enough for them. Mind you there is a faint of background noise but it is only audible when no music is playing. I find the synergy more than adequate with the CK100pro. Love the form factor, simply cant go wrong.
Note: My sansa clip+ was factory refurbished so it might be the fault of my unit. Hope you like your CK100pro. Before buying I advice you to wait a while, there are a number if exciting new dynamic and hybrid IEM are due this year. For example the hifiman RE-600, cardas in ear speakers (which are both dynamic) or he vsonic GR08.
