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.

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

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.

A smoother hexa, and mini-nova. Very clean and balanced all-rounder. Good vocal set. Harman 2019 with more mid-bass, less uppermids and sub-bass. Nothing crazy, but does every genre very well.
