Our Verdict
Vizio SB36512-F6
Vizio V Series V21-H8
The Vizio SB36512-F6 is a better soundbar than the Vizio V Series V21-H8. The 5.1.2 SB36512-F6 has a better-balanced sound profile that's suited for an even wider array of audio content. It also has discrete surround speakers, and it supports Atmos content, unlike the 2.1 V Series. It also more connectivity options and is compatible with more wireless playback options, like Chromecast and Wi-Fi. It can also be controlled via its companion app. That said, the V Series comes with a dialogue enhancement feature, which the SB36512-F6 lacks.
