Our Verdict

Bose Smart Ultra Soundbar

Sonos Arc Ultra

The Sonos Arc Ultra is a better all-in-one soundbar than the Bose Smart Ultra Soundbar. It has a more balanced default sound profile, with better bass extension and an improved center performance, which helps localize dialogue. While the Sonos can't get as loud as the Bose, there's considerably less compression present at max volume. While both are 5.1.2 configurations, the Sonos has a slight edge when it comes to its surrounds performance and supports audio playback via DTS. The Bose is better built, though, and comes with an optical port, which could be useful for users with older TVs. Your decision could also come down to how each bar integrates with other devices in your audio setup. The Bose can pair with the Bose Ultra Open Earbuds Truly Wireless for a more immersive surround sound experience, while Sonos Ace owners will want to take advantage of the seamless audio switching between their headphones and the Arc Ultra.
