I have one, have had it for a few years - ever since they were $199 on Black Friday at Best Buy. Color me UNDER whelmed, way, way, way UNDERwhelmed.
Why? You would think I would pair it just ONCE with the AppleTV that sits just 36 inches away. You would be wrong. It disconnects randomly. I bought it to be an "improved TV speaker" for the downstairs 50" Plasma (yeah, old TV but it works just fine). Thing is, there is absolutely no such thing as an EQ settings for movies, music, concerts, news, sports, sci-fi movies or action movies on the Apple HomePod. So, dialog is often WORSE than what I have on the TV. Yeah, worse than that found on a stand alone TV.
Siri is unaware of multiple instances - so when I tell my watch to set a time for the BBQ grill off the deck, the HomePod used to chime in (cancelling my watch's instance of Siri) and announce that it had no timer. Now, it sets a time without saying anything else - still cancels my watch's timer. And this is the awesome part - when the HomePod timer goes off, no amount of "Siri, Stop Timer", "Siri, Stop that", "Siri, Be Quiet", or "Siri, Cancel Timer" works. The timer goes off chiming constantly without a chance to stop it. Touching the top just has Siri say "Stop Timer", and the chiming continues. So - yank the cord.
The HomePod is a joke. Not a funny, ha-ha joke. An irritating, expensive speaker that barely does what it's designed to do, doesn't play well with your Apple devices (2 Macs, 2 Watch's, 4 AppleTV's , 2 iPads and 2 iPhones) type of joke. It cannot tell when you are talking to your watch, phone or if you are addressing it. It seems blissfully unaware of the networked Music Library of MY SONGS that I like to listen to - I mean, I have tens of thousands of songs on my home network - so when it plays music - and I have songs from the 1960's through today - it plays RAP. And I can assure you I own exactly ZERO Rap. So, it doesn't even recognize the music collection associated with my AppleID, on the network it's associated, with the iPhone it's tied to.
Spend your money on a Google or Amazon device. Sure, they may record you having sex; but at least their products work as advertized.
