Now, is there such a thing as too much of a good thing? The HD 800 is incredibly well-engineered, uses the best components available, tuned with years of research. Biggest drivers used in a headphone, Teflon-insulated, luxurious fabric-coated earpads, etc. But how much is all that tricked-out engineering worth? According to Sennheiser, it's worth about $1399.95, suggested retail. If you want realistic sound, at that price, you might as well fly to wherever to hear your favorite band perform it live.
