Nice vid review on this, definitely agree with a lot of your take on this iem. Alao confirmed with Tangzu themselves that the tips used on these were Acoustune AET07 (white flanges) and AET08 (blue flanges) and the "foams" lol factory mixup but they didn't correct it anymore.
Totally improves it I agree, I just forgot to mention I’m testing unbalanced for the sake of a more general review because not everyone has balanced output choices
