Multipoint is a feature of the headphones, not the phone, so any iPhone works with multipoint headphones. Pair the headphones with your iPhone and a second device, like a Windows laptop or an Android tablet, and they’ll stay connected to both and switch between them.
AirPods work differently. They use Apple’s automatic switching instead of standard multipoint, and that moves them between Apple devices signed in to the same Apple Account. It doesn’t cover a Windows PC or an Android phone.
If your second device isn’t an Apple product, look for headphones that list multipoint on the spec sheet. Budget pairs like the Sony WH-CH720N and the Soundcore Life Q20 (2024) connect to two devices at once.
