Honestly is there any IoT brand that we can trust long-term? Maybe IKEA stuff?
For home audio, Sonos is great. Their voice assistant is completely locally processed.
Sonos might have been good in the past when they were selling a way of streaming your ripped mp3s around your house, they are no longer good now that they think they own the content too.
Sonos has a ~10 year support timeline on their speakers. That's longer than even Apple supports any of their devices, and they're often considered the gold standard of long support of tech products.
I hate being made to defend Sonos twice as it makes me feel like a shill, but it is truly how it is.
