Our Verdict

LG GX Soundbar

Samsung HW-Q800A

The Samsung HW-Q800A is better than the LG GX Soundbar. The Samsung is better built with more wireless playback options. It has better center and Atmos performances, and it reproduces a more extended low-bass. Unlike the LG, it has a graphic EQ for sound customization and built-in voice assistant support. That said, some users may prefer the LG's uniquely sleek design that's ideal for wall-mounting.
