For me, it's a microphone with the identical capsule as KM64, U64, KM84. With a different powering, and a linear circuit like all the other microphones. The housing around the capsule might make a tiny acoustic difference.
The small microphones were never designed to have a personality, or a characteristic sound; they were meant to be linear, so they could be used universally.
