My favorite IEM, the Vsonic GR07 exemplifies who I am as a person. Visually, it's unassuming, but classy. It's sound signature has no alliances with either extreme, and it chooses the path of the middle road. It's what I'd call exquisitely balanced. It's an IEM that I could listen to for hours on end with 100s of different genres of music, and it would never skip a beat due to its versatility. If the 4.A carries this same quality, then I would be honored to own it.
