Could someone explain this to me: http://www.hearotto.com/Products_OT4.aspx ? I’m really not good with engineering. Does “surround” that mean it sounds like you are in a movie theater when you put these on? How do they do that? Is it anything like the thing they have on my TV that “fakes” surround sound (and doesn’t really work that well….)? I just don’t get how you get “surround” out of two speakers, which is what I’m assuming headphones amount to, but maybe there’s some special physics I don’t know about.
how do they create "surround" with only two speakers?
I think it's all based around bouncing things off walls and the like. As Nigel says it won't compare to 5.1 real speakers.
They use a head function to apply various delays and amplitude/phase changes to the sound to simulate what you'd really hear.

Given that you only have two ears and can hear 'surround sound' it follows that it is possible to generate it (to some extent) with only two speakers, particularly if they are headphones as you have more control of exactly what reaches which ear.
It fails for people whose head/ears/brain don't match the standardised functions though.

Thanks for the link, I think I get it now. Heh, that will be interesting. I ordered those Otto headphones, figured for the cheap price it'd be worth it to see how they work. Haven't gotten them yet. I hope my head, ears, brain and nervous system are up to the task. Any idea why they need a battery?
Presumably to provide sufficient power for the electronic wizardry, and jiggery pokery. As someone said, it's all smoke and mirrors type deception - but you need a digital signal processor to modify the sound signal.
Think of all the different effects you can get on your modern hifi amp, to simulate "hall", "church" and "jazz" and stuff. Same sort of thing really.

I got a pair, pretty nice. I don't know if I'd describe it as "surround", but it sure is a nice, full sound. A lot smaller than they looked on the website, too.
