Our Verdict

Sennheiser AMBEO Soundbar Plus

Sonos Arc

The Sonos Arc and the Sennheiser AMBEO Soundbar Plus are both very premium standalone soundbars with Dolby Atmos support. The Sonos has a wider, more immersive soundstage, which is especially noticeable with Atmos content. However, it doesn't come with HDMI In ports like the Sennheiser, and it doesn't support as many wireless playback options like Bluetooth.
