These are all straight stereo gaming headsets,
dont expect any positional audio or 'real' surround sound.
They all connect via straight 3.5mm cable to pc so it is absolutely impossible to get proper positional audio.
The logitech & their ilk are usb connected & have hardware (& software) to process 5 or 7 channels into positional audio.
Its not perfect,its still not real surround sound,but its better than any of the cheap sades headsets will manage.
That said,for 20 euro those sades offer decent sound,have reasonable quality mic's built in & are ok for the money.
They are in no way surround sound headsets though even by the most vague of descriptions.
They are stereo headsets ,nothing more ,nothing less.
If youre running windows 10,you can enable winsonic surround audio in sound properties.(or pay for dolby atmos if you feel inclined)
This wont give you real positional audio,it wont give you an edge in games.
It will make stuff sound more immersive for the most part.
