Expert Audio Engineering Commentary

Tonal Profile

One dynamic woofer, four balanced armatures and two micro-planar tweeters per side, split by an electronic crossover controller. At 37 Ω this is one of the higher-impedance in-ears in the catalogue, which for once works in the listener's favour: source output impedance matters less as the load rises.

Gain Staging Advice

Unlike the rest of the DUNU pages sampled here, this one gives only the milliwatt scale — 107 dB/mW at 37 Ω is about 121 dB/V, which is what a source actually needs to deliver.
