Expert Audio Engineering Commentary

Tonal Profile

The larger 45 mm driver drops the impedance to 37 Ohms and lifts sensitivity to 102 dB/mW, so it needs about half the voltage of the MT5 for the same level — 0.15 V for 100 dB. Two cables are supplied and the socket is on the cup, which is the practical difference from the MT5 rather than anything in the numbers.
