I got into IEM's and headphones last year when I bought the Moondrop Starfield and my EQ journey started because while Starfield sounded very good and definitely the best I heard of any earphone it still sounded slightly veiled, like 80-90% there in terms of image sharpness. After that I first tried AutoEQ, I wasn't impressed and then I found Oratory1990's EQ presets and with some pointers learned to make my own based in FR measurements. This is my 3rd IEM and by far the cheapest. I pretty much already said everything relevant in the pros and cons...
