I still can't get over why my SHE9700 sounds so sibilant. I've burnt them for over 100 hours but it's just not taming down. I love the bass tho... much better than the SHE3580. But with the sibilance at hand, I'd still choose the SHE3580. Is it possible that I may have fakes? Or maybe defects?
Most likely a defect cuz i don't hear any sibilance on my sets whatsoever. The highs are nicely extended but not overly so. Sucks to hear that about your set. : (
