Tonal Profile
A 10 mm ULT dynamic in a metal-injection-moulded shell with four swappable nozzles — two steel, two brass. The nozzles change the treble by a decibel or two; the electrical load stays 32 Ω whichever pair is fitted.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Sensitivity: 123dB/Nrms (@1KHz)»
There is no unit called «Nrms». Every other Moondrop specification sheet — Aria, Aria 2, Chu, Chu II, LAN, Blessing 3 — prints «dB/Vrms», so this is almost certainly a typing slip for volts, and we record it as 123 dB/V. The alternative reading matters: taken as dB/mW, the same number would make KATO about 15 dB more efficient than it is, and every calculation of «will my source drive it» would be wrong in the direction that flatters the earphone. We store what is printed and say plainly that the printed unit does not exist.
