Not that type of IEM. FR-wise, the treble errs on the side of neutral- not tripped up, but not really subdued either. Actually the same could be said of its bass. I can certainly see why fans of the W500 may have expected something different- the W900 is not decadent chocolate. There is certainly some midrange forwardness, but the presentation is thinner, more precise than full-bodied. It's a bird. It's a plane. It's the speed, and the spacious soundstage!
