I keep seeing people posting things about trying out headphones in Guitar Center stores, yet every Guitar Center I've been to doesn't do this. Matter of fact, I went to the nearest one just before buying these DT770's on eBay without hearing them first.
On another note.. seems to me as though all headphones are far from 'flat', which I have yet to really know what that is as far as headphones go. There's no standard for what is flat. It's retarded and makes things difficult. Seems to me like all headphones' responses are just really screwed up in different areas, some not quite so bad as others.. and some in just the right areas that it makes them enjoyable to some people on certain music, etc.. and people perceive it as being detailed and whatnot, so they charge $500 for them or whatever. It's kinda hopeless I guess. Accuracy doesn't seem to exist with headphones.
