Earfun Free Pro 2 or 3? (Patreon)

Recently I was negotiating with Earfun regarding a tuning for the Free Pro 3 by me. But they just offer the option of a 10-band EQ with the default tuning being already pretty bad, thus I cannot offer anything usable for that model unfortunately. I tried convincing them to create the basic tuning on my own, with additional "presets" by them, or offer a fully parametric EQ, or improve their basic tuning by adding some additional filters, but they didn't want to. 

I will still try to create something makeshift as they will pay for it and I need that money, because with Patreon alone I just cannot survive right now, but I can't recommend the Free Pro 3 for sound quality, although I am pretty sure many will still like it for it's heavy bass.

Therefore I will still try to create something for the running out Free Pro 2 based on the neutral tuning I posted here. 

I decided to cover the most common ear canal resonances based on this poll here. I have 8 units and will measure them all, also try finding the spikes to sort those out and finally create an average of all usable units and create 6 different settings for ear canal resonances from 6000hz to 7300hz. These are the most common ones it would seem and I should cover more than 70% of users like this. It will be some work to finish everything and I hope to be able to post something in September for the enthusiast level. 

For others with their ear canal resonance not covered I would kindly ask to contact me directly, and I could create a custom setting for them.
