Earfun Free Pro 2 - "neutral" tuning (Patreon)

This tuning replaces the "smooth" tuning, because they should  be all smooth to some degree, but this one is supposed to sound neutral. This is how I perceive a Sennheiser HD600 more or less.

I tweaked the bass area a little bit compared to the "smooth tuning" and also extended the range of resonance frequencies to 5100Hz and 8300Hz. I cannot measure lower or higher than that, this is the maximum I can offer. This will also be the "standard" tuning for the Earfun Free Pro 2 if you want a neutral representation which should work with my own recordings as well.

Below all measurements at their respective resonance frequencies:
