I got the Gen 2 version. The google assistance for Sonos one need to be improved, a lot. I had a google mini before replacing with this, the sounds are better, but if you want to use voice command to play your music, it is absolutely appalling. If given a choice again, I will get a google home rather than this.
1 star for design.
1 star for sound.

Sounds quite good certainly a better sound than my Google mini. But if you're buying this to work with Google Assistant don't. As other reviews have said the voice response of Google Assistant via the Sonos is quite erratic and overall is poor. I wanted the voice features of my Google mini but a better sound quality for music particularly thru Spotify. I have to run Spotify and the features (eg select, skip, etc etc) manually thru the computer. And even then it is erratic; mostly it works but recently even the connectivity between the Sonos and Spotify is patchy ie the Sonos device just disappears off the Spotify app on my computer without any known reason. I wouldn't buy it if I had my time over.

Sonos one are pretty good for rear speakers when paired alongside sonos sub and play bar. When played on its own the sound is equally crisp and fills the room. I have bought 2 of them and paired with Sub and Sound Bar and it's just outstanding performance. It might break my window glass soon!!

Warning if you buy 1 you will soon be buying more! Superb sound & quality product, integrates with Beam & other Ones to fill the house with music. Cannot fault since buying my 1st Sonos product 1 year ago

We have a lot of sonos speakers. Now sonos wont support them with software updates. I bet they can. We will never buy sonos again unless they change thier policy

It has a great sound but that it where it ends, you can't use this speaker for anything other than Sonos approved music apps but for gaming, movies, YouTube and TV it is absolutely useless, do yourself a favour and go for another brand that isn't so restrictive.

Those familiar with the Play: 1 will feel right at home with the Sonos One. If you''ve in anyway dived into the home automation space, and feel comfortable with Alexa, then I can highly recommend the One. When you take full advantage of voice controls, it just makes life so so much easier. Worth paying the extra, and also worth upgrading, we did!

Firstly, the Sonos One sounds amazing! Huge bass from such a compact unit, very warm sound at all volume levels and no distortion when the volume is turned up. It works great for home automation too with Amazon Alexa. With voice commands, I can conveniently control my streaming music service (Tidal), and my smart lighting (Philips Hue) throughout my home, from almost any room. The microphone and voice recognition is pretty close to perfect. Couldn't live without it.

I have just set up a new Sonos One speaker and found out it has limited useablity with voice control. It uses the Amazon Alexa system to operate. I can’t play music I have on my iPad using voice commands. I need to have a paid music streaming service to work with voice command. It’s not much better than the Sonos play one. It won’t work with all my other Sonos speakers. It’s half baked. I could have saved money and bought another play one. All the manual, iphone or iPad controlled speakers are great. Don’t waste your money until they developed it properly.
