Pros: A full Atmos package with up-firing drivers and a wireless sub, so movies gain height and real bass weight out of the box. Tom’s Guide and Trusted Reviews both gave four stars, praising room-filling sound and clear dialogue. Setup is simple, with HDMI eARC plus optical and aux inputs.
Cons: The sound stays mostly in front of you, so surround effects are limited, and RTINGS found it only fair for music. There is no Wi-Fi, app or DTS support. The sub can dominate at higher volumes unless you turn it down.
