All multi driver 5.1 headphones are pure frauding/scamming:
We hear in 3D because shape of the head causes direction dependant changes to signal received by both ears from sound source.
No matter how big garbage truck load of even wroser drivers is crammed into headphones, they can never create those binaural cues.
And garbage factory used by "Roskat" (=garbages/trashes in Finnish) can't even tune single driver to give decent sound.

So more even worser drivers with less tuning can only create worser cacophony.
Only real way is accurate stereo headphones and two channel signal containing those binaural cues needed by brain.
Which is the job of mathematical algorithms called Head Related Transfer Function.
Those simulate how sound waves coming from sound source are modified by head shape before ears receive them.
Creative has very good algorithms for that, including the one used in Sound Blaster Z serie.
Besides directionality there's also very good feel of distance with headphones accurate enough for binaural sound.
You need to only select headphones as output and enable Surround in SBX Pro Studio tab.
That should automatically change Windows playback channel configuration to 5.1, but it's better to check that manually from Windows sound settings.
From headsets that Sennheiser should be very good.
Open design is lot better starting position for accuracy of sound than closed design, whose only acoustical strength is easy to achieve strong bass.
(though for noisy environment closed design is needed)
Bad/inaccurate headphones simply make immersion collapse completely.
But if you don't actually need microphone, there are very good headphones for gaming around £100 price level.
If you like above neutral bass punch (what your current Roskat likely has) Beyerdynamic DT990 Pro is available for that.
Bass neutral and overall very accurate AKG K702 is again "aural god mode/wallhacking" king for distinguishing details.
