SBX sounds less processed and more detailed, less reverb. For me, I've said multiple times that I think SBX is the clear winner, while Dolby is still very good, but Mad has said multiple times that he hears more accurately placed 6 O'clock rear sounds with Dolby and likes the lightly added bass warmth and reverb. Ultimately, SBX is more precise and Dolby blends sounds that play between two virtual speakers more (ex a sound that would in a theater be playing from both the Back-Left and Back-Right speakers to "appear" to be panned to originate from between them) and adds more "room acoustics" processing, and personal preference is going to rule the day.

I personally hate when I play a game set outdoors but the surround still has some boxed-in "room acoustics," but I've heard worse at that than Dolby.

Switched it out with a cable I had lying around so not sure if the replacement is much good but it didn't sound too different (if any).

They do the same thing, albeit from different points of reference.

 

Dolby headphone uses 5.1 channels to downscale to 2.1 using an algorithm that uses typical speaker placement as a place of reference.

 

SBX uses a sound profile to recreate a 3D space that uses an algorithm to simulate where the sound is going in the game and translating that into two channels.

 

SBX is generally better, as it isn't trying to downscale multiple channels. It has to revert to 5.1 if the game doesn't have a 3D sound profile in it. The issue with Dolby Headphone is the fact that crappy DSPs come with it (except in some Asus cards,) where as Creative actually uses good chips for their DSPs.

I don't think that is true. cmss 3d on the x fi line could do what you are describing, but sbx, I imagine, is a regression to a dolby headphone style of doing things, just because games these days don't give raw audio data to sound cards anymore.

When my friend came over this one time and he played on my setup (Mixamp 2013 back then) he described it as "playing in a soundproof room".

I thought that, but Creative does own the CMSS stuff. It's also called 3DRecon or something on the Sound Blaster soundcards. I had to talk to a lot of customer reps about my X7 not wanting to accept 5.1 (I had the bitrate too high,) and they recommended constantly that I should keep it at 2.1 because 3D sound is game-dependent. I think BF4 was one of those that has a profile that the SBX takes advantage of, but I can't remember off the top of my head.

 

Otherwise, it does resort to doing the dolby-headphone style of things, but it has the advantage of being a newer algorithm that has actually seen improvement over the years. There's nothing wrong with the Dolby headphone-way of things, as using static "speakers" makes it able to take any 5.1/7.1 signal, but Dolby just hasn't really improved their stuff since...god knows when.
