Our Verdict

Sonos Arc Ultra

Samsung HW-Q900H

The Sonos Arc Ultra is a viable alternative to the Samsung HW-Q900H if you're looking for a standalone solution, though the Samsung performs better overall. The Samsung offers a more balanced default frequency response, has a broader suite of sound customization options, and can pass through 4k signals via its HDMI In port. However, the Sonos has a more expansive stereo soundstage, and its side-firing drivers do a better job of rendering surround sound details. Ultimately, choosing between them might also come down to which product ecosystem you want to invest in, as both bars are expandable with aftermarket components.
