This speaker was terrible, not user friendly at all. I had to set it up every time I tried to use it. It's wirelesss connectivity is so poor. The Sonos app needs lots of work.
Cons: Difficult Setup, Difficult to Use, Poor Connnectivity, Unreliable
Bought an ERA100 to be a nice bluetooth speaker while moving into a new house, which rolled into a second one for stereo pairing, then a sound bar, now buying ONE's for remote rooms to bring sound throughout the house. Also added the sub. They're all great, but wish I had bought the ONE's first because they're as good as the ERA's when used in a large system with a sub. The ERA shines on its own, but the ONE is almost indistinguishable from an ERA when you don't need the wider sound field or slightly deeper bass.
Pros: Different Music, Different Rooms, Easy to Set Up, Expandable, Streams All My Music, and More, Superior Sound, Wireless
Living in a rectangular condo with 2 rooms. With the base bar and 6 x One SL, the audio quality, and the clean sound even in higher volumes are top notch. The only downside is the useless Mobile App that needs to be more user friendly and intuitive.
