Right, but you were the one claiming that there were sound bars with Siri, not me. I was simply questioning that assertion.
I have a Sonos Arc, which I’m quite happy with, for what it is. If it had actual first-class Siri support, so I could use Siri to tell the Arc what to play and to adjust settings (as opposed to telling Siri on some other device to stream music to the Arc), it’d be even better. Yes, Alexa and Google Home do better at conversation than Siri - the difference is, I’m willing to let Siri listen to my living room 24/7, where I wouldn’t be comfortable letting either Amazon or Google have a live microphone in my home. And I know there are a lot of other people who feel the same way.
There was a point where I considered getting a pair of HomePods to do something along the lines of home theater, plus music listening in the living room. There was potential there, but Apple kept screwing around and not actually taking the next step. I ended up going with Sonos, and by the time Apple offered the HomePod/ATV support, it was too little, too late. I’d still like to see a proper on-board Siri client for Sonos speakers, but I don’t think that’ll ever come to pass, at this point.
