WHy would you download razer surround when the headset is already functions as a analog 7.1 surround?
I have the head set and what you're doing doesn't make any sense. If you wanted to use razer surround you should have bought the 2.1 version don't you think?
Any headphones can function as a 7.1 headset.
It all depends on what media you're listening to.
If it's gaming, there's usually an option to change the type of sound in the in-game audio settings. For example, changing the in-gam audio settings to "Headphones" or something along those lines will simulate surround sound, whether it be 5.1 or 7.1 depends on how much time the game developers put into audio.
For music it's simple, if they didnt record it in such a way that gives you a direction of where the instruments are, then there is no surround sound.
Bottom line is, you can't force something to be surround sound, and if you say you did, its usually just a placebo.
