Sonos, IMHO, works great when you have multiple speakers setup. They do well because the technology is almost dummy proof and reliable

Edit: was just going through their s1. Seems like most households have 2.75 speakers on average:

As of March 31, 2018, our customers had registered over 19 million products in approximately 6.9 million households globally. Based on customer data, we estimate that, on average, our customers listen to approximately 70 hours of content per month and to approximately 80% more music after purchasing their first Sonos product. We also estimate that our customers listened to five billion hours of audio content using our products in fiscal 2017, which represents 33% growth from fiscal 2016.

Totally this. Sonos’ multi-room support is amazing.

I have 6 different Sonos systems in my house (living room, kitchen, bedroom, workshop, front yard, backyard). It’s wonderful to be able to play audio through any random grouping of speakers, all of which are guarenteed to be in sync as I walk between rooms. You can even plug in an analog source into any one of them (e.g. for a DJ setup at a party) and stream to the entire house — again, all in perfect sync.

They even work in areas where WiFi is weak, because they create their own independent mesh network.

I’ve yet to find anything else that works as reliably.
