Google Nest Audio
While the current Nest Mini is better than its predecessor, if sound quality matters to you then the Nest Audio is the Google Assistant device you need. It’s far better than the Mini, although at this price don’t expect the kind of audio experience you’d get from a Sonos: it gets a little harsh at higher volume and sounds best as part of a stereo pair. It works with all the key streaming music and podcast services.
