The new Apple TV 4K comes with superb Dolby Atmos sound, but the best way to hear it is through the discontinued HomePod. Here's how to do it. You don't know how good something is until it's gone. Still, if you already have two HomePods, or you can find two in stock anywhere, you can use them to create a home cinema effect with your Apple TV 4K. Note, though, it has to be the original HomePods. It has to be two of them. And it also has to be the Apple TV 4K. The one good thing is that it can be either the new or the last generation Apple TV 4K.
