If you don’t have more or less a listening room with the loudspeakers very well placed, you won’t notice a difference. Mono with a good setup will give spatial clues as good as stereo. Yes you might get the left-right mixed up I guess but does it matter?
There was some mp3 matchbox shaking sound clip that really felt like it went around your head (popular maybe 10-15 years ago?), a simple mobile phone produced the effect very well, you just needed to close your eyes.
Audiophiles loathe that crap. It’s not making better sound, just adds loudness and other shit. Surround? It’s like when groups long time ago started using stereo and made the sound Left then Right then LEFT etc. After the first experience its just a nuisance.
But gotta sell the crap I guess. Good they just didn’t care about big corpo :-)
