Our Verdict

Roku Smart Soundbar

Sonos Arc

The 5.0.2 Sonos Arc is a better soundbar for TV shows and movies than the 2.0 Roku Smart Soundbar. Unlike the Roku, the Sonos has a dedicated center channel, which allows it to reproduce voices and dialogue clearly and more accurately. It doesn't downmix surround content into stereo, which provides a more immersive listening experience. Unlike the Roku, the Sonos also supports Atmos content and has a room correction feature and a wider and more focused soundstage.
