What does 'Hearing Aid Compatibility' slider exactly do? And how does it improve sound quality? Only for TCoil or also in direct (bluetooth) streaming?
can it also give louder/clearer sound while streaming voice or music?

Hi geert132,
Depending on the hearing aid model you have, the Hearing Aid Compatibility slider may improve the audio quality. You can learn more about how this can be used with your iPhone here: About Hearing Aid Compatibility (HAC) requirements for iPhone - Apple Support
This setting may improve the quality of voice and music while in use.
Take care.
