The RGB is my new benchmark for technical achievement for IEMs. Its sound separation and its imaging is nothing short of breathtaking. It will produce the sound imaging in space that you had no idea about. Live music sounds like you're in the audience in the front row. BA timbre is there but what makes up for it is just how floaty and dreamy the entire sound gets. Each sound layer has something going on and this is this aspect that really separates the RGB from your traditional hybrid IEMs. Its mids have excellent note weight not too heavy or thick and nowhere near thin. Presents a clean neutral overtone but with excellent timbrally accurate precise sound across the board. Stringed instruments and vocals have always been the forte of the Tansio Mirai IEM and in the RGB. But then it does rock pop and bass genres amazingly well.
