Harman target tuned. Sounds pretty V and contrasty. Not a whole lot of mids. Fairly tasteful. Good sense of separation. Sterile/Lifeless mids and annoying treble. Needs foam eartips.

The May is the way to go if you have 80 bucks. Standard EQ sounds great. Nice low contrast neutral sound

Seems to showcase my least favorite parts of the Harman Target. Lower mids are thin and anemic, treble is overblown and fatiguing. Foam tips help with treble, bass adapter helps with lower mids. Price increase from OG Zero puts it closer to more balanced competition. Just not for me.

A DSP IEM that sounds fantastic with both the Default DSP cable, and a standard 3.5mm analog cable. Great build, good case, and the ability to change the tuning using the Moondrop Link App add up to a fantastic All-Rounder with great versatility and good technical performance. Competes with the Aria 2 and the EW300 very well.

Fun sub-woofer sound in the low-end, nice bouncy textue, but uppermids/treble can be too bright, especially with 15K treble peak. Basically a more v-shaped version of the OG TE Zeros. Vocals can be a bit shouty and thin.

The Moondrop May offers a convenient USB-C DSP cable with multiple EQ presets accessible via the Moondrop Link app, though the app suffers from connectivity issues and requires invasive permissions like location and file access. Its lightweight resin build provides solid comfort for extended wear, but the included ear tips are notoriously difficult to install on the nozzles. The DSP cable itself can exhibit a faint electronic whine during audio pauses, which disrupts calls or quiet passages.

Sonically, the May delivers a balanced signature with smooth, natural midrange, though male vocals occasionally lack resolution and texture. The 6mm planar driver handles treble with refinement, avoiding harshness, but struggles with airiness and micro-detail retrieval compared to competitors like the Truthear Hexa. Bass texture and layering also fall short despite the hybrid 1DD + 1 planar configuration, leading to a somewhat one-dimensional low end in complex tracks.

Technical performance is adequate for the price, with a moderately intimate soundstage and competent imaging, though instrument separation and dynamics can feel congested in busy mixes. The May scales better with analog cables than its own DSP solution, revealing improved clarity and midrange texture when bypassing the stock setup. While the DSP concept is innovative, execution issues limit its appeal, making the May a competent but inconsistent package at $65.

Average Technical & Tuning Grades

Average Tunign Grade

B-
  • It sounds pleasant overall, with some uneven spots that hint at room for refinement. Vocals remain pleasant despite the imperfections.

Average Technical Grade

B-
  • An honest, middle-of-the-road performance preserves structure without chasing micro-detail. It's respectable for everyday listening sessions.
Bass A+
You hear powerful yet disciplined low-end slam that extends effortlessly. It marries sub-bass depth with great texture.
Mids B+
Midrange presence is good, delivering clear vocals and solid texture. Voices come through with pleasing clarity.
Treble C-
Highs are present enough yet carry a bit of grain and splash. Busy mixes can still feel a bit splashy.
Dynamics C+
Expect solid impact overall, even if finer gradations feel a touch smoothed. Micro-details could still be sharper.
Soundstage B
Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.
