Professional reviewers commend the Signa S2 for its dialogue-enhancing VoiceAdjust™ technology, solid midrange performance, and straightforward HDMI ARC integration, noting it outshines budget rivals like the Bose Solo 5 but criticizing its lack of immersive surround, limited codec support, and absence of smart-home features.
Everyday users overwhelmingly praise the sound bar's ability to make dialogue clearer and its hassle-free installation, with many calling it a noticeable upgrade over TV speakers; common complaints revolve around Bluetooth reliability, a small remote, aggressive power-saving shutdown, and the dusty fabric grille.

Professional reviewers praise the VIZIO 5.1 Soundbar SE for delivering realistic surround thanks to its physical rear satellites and strong bass, while noting the lack of an optical input and that Atmos is simulated rather than driven by up-firing speakers.
Everyday users consistently highlight crisp dialogue, powerful bass, and immersive surround, while expressing frustration over the missing remote, occasional Bluetooth/subwoofer dropouts, and the clunky app interface.
