Yesterday I was finally able to try these. To be honest, I'm kind of dissapointed. The detail retrieval is nowhere as good as I would expect from a highly-priced, 3 balanced-armature IEM. Audio Technica CK10 smokes these in terms of both detail and instrument separation, with "only" 2 drivers and roughly half of the price. Actually, even the single dynamic driver RE272s excel the Shures in those terms.
They also do not perform as good as CK10, Brainwavz B2 or RE272 with complex music. The Shures sound way too congested.
I can't deny though that the Shures are more fun to listen to than the previously mentioned.
