Our Verdict

Vizio M Series M51a-H6

Samsung HW-Q65T

The Vizio M Series M51a-H6 is a better soundbar than the Samsung HW-Q65T. The Vizio has a more extended low bass and a more neutral sound profile out of the box. It also supports Dolby Atmos content. However, the Samsung is better built and has a graphic EQ for sound customization.
