Is it possible to obtain a almost perfect sound stage (like mid and hi-fi home systems) using headphones ?

Most headphones will produce an interesting binaural headspace that is somewhat different to the soundstage that a pair or more of speakers produce. This headphone soundstage ranges from a relatively narrow space (Grado) to a wide one (AKG). In some ways, headphone soundstage can be eerily realistic, almost making you think someone is standing just behind you. That's also the problem, the soundstage is only really extended left, right, and perceptually at some distance though it can be unclear to the processing mind whether it is in front or behind.

There have been some reasonably successful attempts to master this issue, most notably the development of the earspeakers. Do a search on Jecklin Float or K1000 for examples. They're very expensive, kind of ridiculous-looking, and yes, can achieve something like the soundstage of a decent stereo system. If you want to get even more ridiculous, do a search on the Sennheiser Surrounder (or "Soundkragen"), or if you dare, on the dreaded Phonodome.
