well, they could be custom, but all knowles’s driver family have same diaphragm and housing, just different coils for impedance.Kan Andromeda uses 5 drivers not from the aftermarket, maybe those 5 drivers match the size and physicality of other products such as knowles rab, bk, ed ... or sonion ...?
Except RAB (maybe), a few of those drivers pretty different response, even under test conditions (low impedance amp so that driver impedance barely affects response)
I doubt it’s sonion, they don’t have a vent on their models in that spot, and their metal housings look different.
