Yep, you can pair 2 HomePods together to act in Stereo, then just AirPlay to them.
You pair them using the Home app.
Great for Music and Video, a slight delay for system sounds / games.
Yep! You can! I use this for my AppleTV in a living room, and use it with my laptop fairly often too. No issues.
The U.S. low price point right now seems to be ~$200 U.S. Currently Best Buys's price.
So for those of you that have paired 2... is the sound that much better? (I think the sound from one is pretty terrific!)
