Every pair of headphones has two drivers unless you're using garbogio multi-driver headsets. R6 siege is designed around stereo usage as is. I was a big proponent of simulated surround sound but I've been won over by straight stereo over the last week.
SBX/Dolby neuter the other wise excellent imaging of the HD-800-S'.
Well there's give and take by going straight stereo.
If you're not using virtual surround, you're getting to hear your headphone as it sounds... like the headphone it is.
When you use virtual surround, you're listening to the headphone emulate a room full of speakers. It isn't supposed to sound anything like what you expect from the headphone.
It is this distinct difference that people STILL keep failing to understand. When you use virtual surround, you have to understand that you're no longer listening to headphones. You're getting a representation of a room full of speakers done by those headphones. They're gonna sound COMPLETELY different.
A more proper comparison is a headphone with virtual surround vs a room with 7 speakers. That is the most COMPARABLE uhh...comparison.
To the people complaining about how virtual surround changes how headphones sound. Well, that is because it's no longer supposed to sound LIKE HEADPHONES.
With that out of the way, you can make a choice:
a. Stick to stereo, where the fidelity is higher, and your headphones sound as they were intended. Drawback being no front/rear indication, which vastly limits your perception of the virtual space and where sounds are actually coming from relative to your 'character' in video games.
b. Go with virtual surround, where your headphone is figuratively transformed into a room full of speakers, with all the benefits of being able to hear where sounds are coming from in any direction, without the expense of actually having a speaker setup. Drawback being that objectively, the sound quality is altered in a significant way from what a headphone was originally intended to sound like.
I will always call it nonsense to anyone who says stereo gives better positional advantage over virtual surround. There is nothing better than getting an accurate representation of where a sound is coming from, as if the sound was actually being played in front or behind you. All stereo can do try and make a sound seem different in tone between front and back, and actually not being able to move the sound in the virtual space to account for the front/back.
Thankfully, more and more games have built in virtual surround options, Xbox has Atmos, etc. These things are making virtual surround more and more common, which is a benefit to all.
And as always, it's best to stick to plain stereo for nearly any stereo source like music, and any other source that wasn't made with surround in mind.
