Our Verdict
Samsung HW-T650
LG GX Soundbar
The LG GX Soundbar is a more versatile 3.1 setup than the Samsung HW-T650. The LG's surround performance is better, and it can play Atmos content, though it downmixes it to stereo. It also supports eARC as well as DTS:X, and it can passthrough 4k @ 60Hz. The LG even has a companion app that allows you to save audio playlists and access a dialogue enhancement feature. However, the Samsung feels better built. While it can't get as loud as the LG, it can reach its max volume with less compression.
