I've been thinking about buying a pair of HD598 & have read a few reviews on Head-fi but I also came across the review by Steve Guttenberg on CNET dated Feb. 21, 2011. In his review Guttenberg mentioned something interesting : (copy & paste)
"The HD 598 features Sennheiser's Eargonomic Acoustic Refinement technology, which uses acoustic baffles inclined at a slight angle to guide the sound directly to the ears. The technology appears to be derived from Sennheiser's flagship HD 800 headphone. The HD 598 also features powerful neodymium magnets, Duofol drivers, and lightweight aluminum voice coils."
Does anyone understand this to mean that Guttenberg refers to the "soundstage" of the HD598. I haven't read this thread from the beginning because of it's length so if this specific subject has already been addressed I apologize.
Thanks and looking forward to feedback.
