What reviewers say
Both praise controlled bass, clear dialogue and unusually convincing stereo music, while noting the missing HDMI input and display. What Hi-Fi finds precise, expressive cinema sound; TechRadar prefers rivals for height and surround immersion and criticises the app and remote. Both consider it a capable standalone system.
