I'm in the process of finding some fantastic immerive headphones for single player games. It's my understanding that headphones technically don't have surround sound, it's just an illusion created by drivers. Which I'm fine with. I keep seeing headphones advertised as 7.1 and they seem to be the top of the line "surround sound" gaming headphones, should I be looking for 7.1 headphones or do I have other options, like a sound card or whatever? I began this headphone search thinking that it'd be the easy part but it turns out that I don't know what I'm doing.
Basically I'm just looking on advice that'll aid me in my search, because currently if I see headphones that might look great, but aren't advertised as 7.1 surround sound, I feel like I shouldn't consider them.
