The Sony HT-G700 is a slightly better performing soundbar overall than the Sonos Arc. The Sony is a 3.1 channel can produce a more punchy, boomy bass thanks to its wireless subwoofer, it can get a tiny bit louder with less thumping and compression artifacts, and it has EQ presets available. It also has a Full HDMI In port that supports all common formats, and you can use Bluetooth to stream audio content directly to the bar. However, the Sonos is a 5.0.2 channel that feels slightly better built, and it has a room correction feature. It also uses side-firing speakers to reproduce surround content as well as up-firing speakers to reproduce Atmos objects, which is better than the Sony.
