The DARK SABER is a wired in-ear headphone from Moondrop, a well-established Chinese manufacturer known for accomplished, measurement-informed in-ear engineering, built with an extraordinary sensitivity. The DARK SABER brings Moondrop's considered engineering to a serious wired in-ear format.
Key specs that matter
Frequency response spans an exceptionally wide 7Hz to 41,000Hz within plus-or-minus 10dB - a remarkable range extending well beyond typical in-ear specifications. Connection uses a 3.5mm jack. Sensitivity is an extraordinary 128dB SPL at 1kHz/1mW - among the highest efficiency figures available in any in-ear headphone - with impedance at a comparatively benign 22 ohms.
Sound and use context
Expect explosive dynamic headroom reflecting the extraordinary 128dB sensitivity combined with the exceptionally wide 7Hz-41kHz bandwidth, meaning this in-ear reaches satisfying volumes readily from even the most minimal source output.
Pairing
The extraordinary 128dB sensitivity and comparatively benign 22-ohm impedance make the DARK SABER compatible with virtually any source, including the most modest portable devices, though care should be taken with high-power desktop amplifiers given the extreme sensitivity.
Alternatives
Moondrop's own ILLUSTRIOUS offers a related model with an even wider bandwidth within the same broader in-ear catalogue.
