Can I connect two Sony speakers to my iPhone 15 Pro Max?

To connect two Sony Bluetooth speakers to your iPhone and play audio simultaneously, you can use Apple's Audio Sharing feature (if supported) or Sony's Party Connect feature, depending on your speaker models.

Sony's Party Connect feature allows compatible speakers to sync and play audio simultaneously. To check if your speaker are compatible, look for this feature in the speaker's manual or specifications. If it does, then the manual should also provide you the steps to do so.

For Apple's Audio Sharing, if both speakers have Bluetooth and are connected individually, this may not work natively, as Audio Sharing is designed for AirPods or Beats. However, you can try using third-party apps, something like AmpMe.
