Expert Audio Engineering Commentary

Tonal Profile

Open sibling of the 1770 MK II, same TESLA.45 driver, one decibel less sensitive. 94 dB/mW at 30 Ohms is a low figure in absolute terms — it needs roughly 40 mW for 110 dB, more current than any phone will supply — so the low impedance buys compatibility, not ease of driving. Those are different things and the marketing conflates them.
