Conditions have t ralises by listening to records and testing Syrius Das Microfon. Each headphone will then pass the "roping frquentielle" Pink Noise 1/3 October 20 20khz and frequencies sinusodales 20 20Khz still octave.
The 240m reveals a good balance across the spectrum of frequencies and good spacialisation. The balance, dynamics and timbre of the instruments are perfectly respects uncolored particulire. Not be very accurate surgical.
Very good monitoring headphones as the name suggests. Personally Impedance of 600ohms is not a handicap condition possder a linear amp with good power only feature. This Impedance Leve participates in excellent rendering of this headphone.
