Our Verdict
LG SN9YG
Samsung HW-Q70T
The LG SN9YG is a better soundbar than the Samsung HW-Q70T. The LG offers better surround and Atmos performances, and it reproduces a more extended low-bass. It comes with more sound enhancement features like room correction and auto-volume mode, and it has built-in voice assistant support. It also supports Chromecast built-in. That said, the Samsung has a graphic EQ for sound customization, which some users may prefer.
