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.
