Since there are only two speakers w/ headphones any 5.1 headphone setup is<br>
going to be a bit of cleverness.<br>

I may state the obvious, but you do realise that you only have two ears ?<br>

One of the interesting things about the human ear is its shape actually conveys some position information -- besides the left/right info we get from having two ears, the shape of our external ears alters the frequency response in the front/back and up/down direction, and our brains use this to help determine the positions of sounds. So the idea that a pair of headphones could approximate a surround sound experience isn't totally ridiculous.<div>

If the directional characteristics you mention are true of the ear, perhaps these headphones attempt to take advantage of that aspect of the ear design. <br>
