Fairphone Fairbuds — Web Bluetooth Control
The official built-in presets available in the Fairbuds app. “Studio” solves some issues of the “Main” preset, but still noticeably lacks in treble.
A collection of presets generated with AutoEq based on frequency response curves from different sources. They use undocumented parts of the protocol to achieve greater accuracy.
Due to different anatomy, no completely-universal neutral earbud target can exist. These presets should serve as a good base but in the end they are tuned to my personal preference; see this page for how to generate your own.
Presets using only settings exposed by the official Fairbuds app. Use these if you want to play with the values, as they have a constant band width. You will not achieve as good a treble response though, as the EQ stops at 12 kHz and does not affect higher frequencies enough.
