Tonal Profile
Open-back, individually matched drivers, MMCX connectors, and the lowest sensitivity in this batch: 96 dB/mW at 65 Ohms wants about 1.1 V for 110 dB. That is the quiet end of what an interface headphone output manages, which puts the 1840 in the same practical bracket as a 250 Ohm beyerdynamic despite the far lower impedance.
