Tonal Profile

The MK II is where beyerdynamic finally names the unit — «95 dBSPL (1mW/500Hz)» — and where it abandoned 250 Ohms for 30 Ohms on its flagship closed monitor. The company states the reason outright: playback devices lack the output voltage for high-impedance loads. That is the same argument the catalogue's own DT 880 PRO page does not make.
