Improve the audio accuracy of third-party Bluetooth devices
You can improve the sound of third-party Bluetooth devices by specifying the Bluetooth device type (such as headphone, speaker, car stereo, and more) on your iPhone.
- Go to Settings > Bluetooth, then tap next to the name of the device.
- Tap Device Type, then choose the type of device.
Could this be the issue? This wasn’t in iOS 16. Although saying this, there isn’t any issues occurring in iOS 17 with iPhone 15 as far as I am aware and also have tested my audio with my wife’s iPhone 15 and she has no such issues. Just the Pro models… Plus can’t change the device type of hearing aids, well Oticon anyway since these are paired in Accessibility rather than in the Bluetooth area.
I have sent logs to Apple as they contacted me and installed diagnostics logs on my iPhone 15 Pro so they should be reviewing these today and hopefully find the issue and fix it.
