Apple has a headphone companion app
Rather than it’s own App (like the
Apple Watch) Apple’s “
Headphone” settings are buried in the “
Accessibilty>Audio/Visual>Headphone Accomodations” section of the Settings App.
In fact most iPhone users do not even know it is there. I found out about it from a short YouTube video.
The 3 available settings are quite vague and only have 2 or 3 options per setting.
(As confirmed by a previous post Oratory’s measurements show Vocal Range - Moderate to bring it closest to the target)
And this is not to be confused with the EQ presets in “
Settings>Music>EQ” which only applies to playback in the Music App.
I can access “
Headphone accomodations” on the iPhone, but apparently it only has effect when you have Apple Airpods connected.
