| Comparison Aspect | True Surround Sound | Virtual Surround Sound |
| TV Audio Output Format | Passthrough | PCM |
| TV Port & Content Format Requirements | HDMI eARC port, Dolby Atmos source | HDMI eARC or ARC port, standard audio source |
| How It Works | Uses multiple physical speakers to play different audio channels from different positions | Uses audio processing and acoustic algorithms to create a virtual surround sound experience |
| Sound Position Accuracy | Very high: Precise sound positioning, ideal for movies and gaming | Medium to low: Creates a sense of spatial direction, but positioning is less precise |
| Sound Field | Wider and more immersive, with a more complete physical surround sound field | Creates a wider sound field through virtual processing |
| Immersion and Realism | Strong immersion: Creates a more realistic cinema-like experience with effects such as footsteps, gunshots, and explosions | Moderate immersion: Creates a spacious stereo/surround effect, but without the same physical depth as true surround sound |
| Sound Detail | Different physical speakers handle different audio channels, providing clearer channel separation and more precise sound positioning | Audio processing creates a wider sound field, and the surround speakers also reproduce vocals and dialogue, similar to the main soundbar, rather than being limited to sound effects |
| Installation Complexity | More complex — requires positioning and connecting multiple speakers | Simple — typically requires no additional surround speakers |
| Cost | Generally higher | Generally lower |
| Ideal Use Scenarios | Home theaters, high-end gaming, movies, and immersive entertainment | Small-space entertainment, casual viewing, and daily use |
| Example Products | 5.1 Poseidon D60 or 7.1 Poseidon D80 systems supporting true surround | Soundbars such as 5.1 Poseidon D50 or 7.1 Poseidon D70 or 7.1 Aura A40 with virtual surround support |
| Pros | ✅ Accurate sound positioning | ✅ Easy setup |
| ✅ Rich and detailed sound field | ✅ Budget-friendly | |
