Adding a second ‌HomePod‌ to your setup enables stereo sound to create a wider soundstage for richer, more enveloping sound.

Each ‌HomePod‌ is able to play its own audio channel — left or right — while separating out both the ambient and direct energy. This provides a wide, almost three dimensional soundstage for a more immersive listening experience anywhere in the room. A ‌HomePod‌ stereo pair also creates greater bass extension, resulting in a deeper, more accurate reproduction of low frequencies.

Both the ‌HomePod‌ and HomePod mini support stereo pairing, but be aware that you cannot pair a ‌‌HomePod mini‌‌ and an original ‌‌HomePod‌‌ together. You can only pair two original HomePods or two ‌‌HomePod‌‌ minis as stereo speakers. It's also worth bearing in mind that when two ‌HomePod‌ speakers are joined, only one responds to Siri requests, plays alarms, and acts as a speakerphone.

You can join two ‌HomePod‌ speakers as a stereo pair when you initially set up ‌HomePod‌, or you can later join two speakers that you’ve already set up using the Home app.Keep reading to learn how it's done.

Once you've paired the two ‌HomePod‌ speakers, you'll see a single pane in the Home app representing the stereo pair. If you touch and hold it and tap the cog icon, you'll see an Audio Settings option. You can switch the left and right channels by tapping it and following the onscreen instructions.
