I have a set of the JVC 4-channel headphones like those pictured above. I bought them off eBay, and the seller even had his original sales receipt in the box from the Base Exchange. They sound pretty good, but are very heavy and hence tiring to wear for long. Also, the 4-channel effect in the older headphones is only so-so, the drivers just seem to be to close together. I do have a set of modern gaming headphones, and my Creative Sound Blaster card in my computer does a really stunning job of doing surround sound. One of the demos it has is of a helicopter flying around your head, and it is very, very convincing. Also, when I'm gaming, you can definitely hear things from all around (like when someone shoots you from behind.) I'd say the modern headphones get the edge here.
