“The following is taken out of its context from my review here http://www.head-fi.org/t/687962/asg-2-ck100pro-and-ue900-reviews-the-dysfunctional-family I just thought that the CK100Pro deserved a review here.

The bass might even be overpresent for some (it is the Bass edition though), but the key fact for me...” --BlastAway
“I prefer the GR04 to my Visang GR02 and greatly prefer them to my Soundmagic PL50 (I don't like the PL50). This review is not going to get technical.

Coupling intuitive pivoting tips with a reasonable balanced sound signature, the Pro Flagship deserves far...” --thecansmancan
