Sennheisers and modmic FTW

That's the setup I plan on getting.
Headfi is a great place btw.
Seriously, after researching surround sound headphones and positional audio I realized that all those Gaming Headsets are a gimmick. There is no such thing as hardware "Surround" these gaming oriented Headsets as they only have one set of drivers per side. Multi driver headphones exist but they are not that great (I hear) given the small headphone space not allowing adequate distance separation between physical drivers. Then there are those USB headsets that say they are 5.1 or 7.1 headsets. Well, They are plain old vanilla stereo headsets with fancy verbiage since they have 2 drivers, not like a 5+1 or 7+1 speaker setup. They come with their own 3D software/Sound driver that takes apart the stereo stream and emulates a multi-positional space. However these implementations don't all sound that great IMO. I tried Creative's CMSS-3D and SBX along with Razer 3D surround implementations (CMSS and SBX are creative soundcard implementations). You can actually download a free version of Razer 3D to use with your own Headphones to try it's attempt at 3d sound augmentation. It's the same software that comes with their line of Headsets. The software manipulated 3d positional emulation was always odd in some way for me and caused artifacts.

Creative did offer SBX Software at one point that was a software solution to what they implement in their current cards for only for 9.99 and I tried it but never stuck to using it.
I found that a quality high end Open Headphone with a wide sound stage sounds the best. Open headphones give the best dynamic sound stage. Then just pair it up with something like Modmic. Head-fi.org was a great place to learn.
Test your Headphones with Virtual Barbershop, it's an amazing demo of what a good stereo headset can do. Very Trippy when you close your eyes.

Another good positional sound test:

Anyhow, just some input from my own research for what it's worth. I'm not an audiophile expert so this is just a layman summary of what I learned in the process
Take Care.
