## At a glance

- The system is listed with two rear and two front wired surround speakers alongside a wireless subwoofer.
- HDMI eARC, optical and AUX inputs provide several listed ways to connect a TV or older device.
- The app is claimed to offer EQ presets and six named listening modes, including Movie, Music and Night.

## Pros

- Four wired surround speakers are listed, giving buyers a multi-speaker layout rather than a soundbar-only setup.
