My Apple ecosystem as a web developer forced to use Windows:
iPhone 17 Pro
iPad Pro 11-inch
Apple Vision Pro
AirPods Pro 3
AirPods Max
Apple Watch Ultra
HomePod 2 (stereo pair)
Apple TV 4K
Mac mini M1
Windows PC 💀
I recently discovered a way to get a pair of HomePod 2s in stereo mode to recalibrate much faster.
Basically, play “My Lord” by Yarin Primak at a relatively high volume. In the video, I shake one of the HomePods to force a recalibration. Right after that, you’ll notice the sound is coming mostly from the center instead of filling the room properly.
When I play My Lord, around the 0:40 mark you can actually hear the soundstage expand. After that point, the HomePods seem to be fully calibrated again. Specifically, something in the opening section of the track appears to trigger the calibration process.
TL;DR: If your HomePod 2 stereo pair seems out of calibration, try playing the first 40 seconds of “My Lord” by Yarin Primak at a higher volume. Other songs can work too, but this one seems to trigger recalibration much faster for some reason.
