Google Nest Audio vs Sonos Sub Mini

They are not the same kind of product, so the answer depends on what you need. The Google Nest Audio is a complete Google Assistant smart speaker that plays music, answers questions and groups for multi-room audio, and it costs far less. The Sonos Sub Mini is a subwoofer with no microphone and no built-in playback, useful only as an addition to an existing Sonos speaker or soundbar.

No. The Sonos Sub Mini is a wireless subwoofer designed to be bonded to a Sonos soundbar or speaker such as a Beam, Arc or Five. It has no microphone, no voice assistant and cannot play music by itself, so it is only worth buying if you already own a Sonos system.

No. The Google Nest Audio is a Google Assistant smart speaker, not a subwoofer, and it does not join a Sonos system. To add bass to Sonos speakers you need a Sonos subwoofer, and to add voice control to a room the Google Nest Audio is the one that does it.

Only the Google Nest Audio does. It has Bluetooth alongside dual-band Wi-Fi, which makes quick pairing from a phone easy. The Sonos Sub Mini has no Bluetooth and joins a network over Wi-Fi or a wired Ethernet cable.

The Google Nest Audio. It works with Google Home and Home Assistant, is a Google Assistant speaker and can act as a Matter bridge. The Sonos Sub Mini has no voice assistant and is not an addressable target, though it does integrate with Home Assistant.

Someone who already owns Sonos speakers or a Sonos soundbar in a small or mid-size room and wants deeper bass without stepping up to the larger Sonos Sub. For anyone without a Sonos system, the Google Nest Audio is the more useful purchase.
