Our Verdict

Samsung HW-Q950A

Vizio V Series V51x-J6

The Samsung HW-Q950A is a better soundbar than the Vizio V Series V51x-J6. The Samsung is an 11.1.4 setup that supports Dolby Atmos content and offers built-in voice assistant support, unlike the Vizio. It's better built, with better soundstage and surround performances. It also comes with more sound enhancement features, like room correction and a graphic EQ, and it can get louder.
