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

This tuning is meant for those who get too little bass and perceive upper mids as too harsh with the "neutral" tuning. I call it "mainstream" tuning as it should offer a similar sound to "neutral" but with more bass and less upper mids. Below you can see a measurement of both:

Here all available "mainstream" tunings measured at their respective resonance frequencies:

I am offering a range of 5800-7650Hz which should cover more than 90% of ear canal resonances based on the values I got here. Measuring lower or higher values than this is quite cumbersome, those are covered with my "neutral" tuning.
