Our Verdict

LG GX Soundbar

Samsung HW-A650

Depending on your listening habits, you may prefer either the Samsung HW-A650 or the LG GX Soundbar. The Samsung has a more neutral sound profile out-of-the-box, and it comes with a graphic EQ for sound customization. It's also better-built. However, the LG has a better soundstage performance, supports Dolby Atmos content, and offers support for more audio formats. It can also passthrough the highest quality bandwidth signals.
