I tried that app, Joe Hisaishi EQ really felt like the most neutral out of all presets, but I eventually returned to using Dynaudio presets because I have a Oneplus phone which includes stock app for these buds integrated into Bluetooth menu, and I found Chinese HeyMelody draining my battery in standby. Also I don't find the difference between Hisaishi and Crisp&Clear too drastical to have a choice between them, but maybe I reconsider that later because Hisaishi EQ sounds good.

Enco X Classic - I hate that present. Really. It's fatiguing to me. Like typical cheap IEMs. Also I find myself using Dynaudio Realistic a bit more often than any other preset.
