It supports Dolby Atmos, HDMI eARC, Wi-Fi 6, Bluetooth 5.3, Apple AirPlay 2, Sonos Voice Control and Amazon Alexa, Trueplay, Speech Enhancement, and Night Sound.

Key to next-level immersion
Sound Motion™ technology redefines what’s possible in audio performance. By integrating Sound Motion™ into Arc Ultra, we’re able to obtain a deeper, more powerful bass response in a smaller package. This innovation frees up space for additional tweeter and mid-range drivers, delivering a more expansive and balanced soundstage, surpassing the previous generation of Arc.
Beyond immersive
Pair Arc Ultra with a Sonos Sub and Era 300 rear speakers for the ultimate Dolby Atmos surround sound experience, with bass you can feel and jaw-dropping detail from every direction.2 Make the experience all your own with a pair of Sonos Ace headphones.
Crystal-clear dialogue for every listener
Speech Enhancement with Arc Ultra uses AI to detect the human voice and clarify dialogue. With four customisable levels, you can ensure every listener hears every word with precision.
