It’s a better-than-average simulation of Dolby Digital or Dolby Atmos. Better than tv speakers or a sound bar. But the proper configuration has the two speakers positioned 6-8’ in front of you near the TV. The sound won’t magically wrap around your head and appear to “surround” you.
You also need an Apple TV and decent wifi. It’s a completely wireless sound system (wifi, not bluetooth) so it can be temperamental if you have weak signal, interference, etc.
If you’re paying for something you haven’t enjoyed in “months”, that’s kind of a you problem.
