Pros: A dynamic and planar hybrid that came with a USB-C DSP cable and app presets, and measures well across 20 measurements (score 75) with full sub-bass to 20 Hz.
Cons: Discontinued, so it is mainly found used. Treble sits about 2.6 dB below target, a slightly dark balance.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the Moondrop May measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the median of 20 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 20 measurements from the squig.link databases of ankramutt, audioamigo, bassyalexander, bedrock, boizoff, cammyfi, csi-zone, fahryst, fernandagunsan, harutohiroki, hobbytalk, hu-fi, jaytiss, kr0mka, lumerion, musicafe, precog, soundignity, superreview and suporsalad.
