Our Verdict

LG SG10TY

Sonos Arc

While the Sonos Arc and LG SG10TY occupy a similar price point, both soundbars are very different in terms of setup. The Sonos is a well-built all-in-one soundbar that delivers a better soundstage to give you a more immersive sound. Unlike the LG, it doesn't have to downmix surround content to play it, which can help improve the localization of sound objects like voices. That said, the LG has better bass extension since it has a dedicated subwoofer. It also supports a lot more connectivity options, including HDMI, so you can use the bar to passthrough content from your device, like a console to your TV, and wireless connections like Wi-Fi.
