I think all Sonos speakers, except the Era 300, have a wonderful design and are easy to use and setup. The audio quality, while not true audiophile sound quality is superb for the small design.

Have a look at this page for what the lights mean.

Google is your friend… most of your questions can be answered on Sonos’ support site.

thanks Pools, i have of course googled this.  pressing and holding the button on the back for various amounts of seconds works sometimes, and does not work others.  why one button? why not a pairing button? it is terribly unintuitive, and a quick google search let’s me know i’m not the only one with this feedback.

It’s the worst Sonos speaker I own. Also worst Bluetooth speaker. Frustrating to use. The one button thing is a pos.
