I like my (big) Homepod stereo pair for music, though I'd be disappointed if I'd paid full whack for them. There are lots of redditors making outlandish posts about how a single Homepod pressurises their warehouse-sized apartment and anything above 15% volume makes their bones crumble with the depth of the bass, but really, they're a £200 speaker and always should have been. My Naim Mu-So is a quality streaming speaker, Homepods are glossy sound that's listenable but isn't really convincing and I'm definitely no audiophile.
Siri, however, is appalling.
"Hey Siri, play music" (plays music on my iphone instead of Homepod)
"Hey Siri, play something different" (maybe it'll start playing separately on my phone when it was already playing on the Homepod).
"Hey Siri, stop!" (maybe it'll stop, maybe it won't. Maybe the music volume will drop and maybe resume a moment later)
Then there's the issue with the music controls appearing on my iPhone lock screen for a while, before magically disappearing so I have to revert to voice control.
Siri is really terrible and it's making me half-wish I'd just gone with Sonos from the outset. The only thing holding me back is always-on listening services from Google and Amazon which I don't want to bring into my house, but Google Assistant is worlds better than Siri and I can't understand why Apple think they have a viable product.
