By aspect — in detail
Well liked in quality — a clean, sub-bass-focused low end with good extension and tactility that doesn't bleed into the mids. Quantity is where reviewers split: one camp hears it as big, potent and basshead-level, while another hears a substantial-but-safe sub-bass shelf — plenty of slam for most, short of a true basshead tuning. A minority of critics find it merely 'safe.' Seal and tips move it, since the lift is sub-bass-led rather than mid-bass-boomy.
Measured
ASR's 711-coupler measurement shows a sub-bass-leaning shelf that tracks Amir's target closely; Audio Discourse describes the bass as 'slightly above neutral with a … focus on sub-bass,' and Bedrock hears 'excellent sub-bass extension' with 'average bass texture' — a sub-bass tilt more than a mid-bass thump, which is why the 'basshead' vs 'safe' read tracks how much sub-bass a given listener wants.
Where it splits
Big, potent, basshead-level low end.45%
“I would define it as a basshead level of bass rather than bass for neutral enjoyers.”
Headfonics (Kurt)
Substantial but safe sub-bass — satisfying for most, not a basshead set.55%
“Although this isn’t a basshead IEM, most listeners should be satisfied with the amount of slam and impact.”

The other main fault line. Nearly everyone agrees the planar-fed top end is smooth, refined and non-fatiguing, with little sibilance — a plus for treble-sensitive and long-session listeners. The split is over what that smoothness costs: one camp is happy with a clean, easy treble, while another hears it as safe to the point of dark, short on air, sparkle and top-end extension. A few note real planar sparkle and 'excellent' detail, so how it lands depends on your ears, tips and EQ preset.
Measured
The 6 mm annular planar handles the region above ~8 kHz for lower distortion and smoothness; ASR notes the passive response sits within 2 dB of target until a dip around 6 kHz. Same tuning, two readings.
⚠ vs. listeners — One smooth, slightly-relaxed top end is heard as 'refined and non-fatiguing' by most and as 'dark / lacking air' by detail- and sparkle-seekers. Preference and program material move it more than any single 'true' treble does — and because the MAY is EQ-first, a shelf filter opens the top for those who want it.
Where it splits
Smooth, refined and non-fatiguing — clean planar treble, no harshness.55%
“There isn’t much harshness or excessive brightness to it at all, rather it’s smooth and clean.”
Headfonics (Kurt)
Safe to the point of dark — short on air, sparkle and extension.45%
“a focus on the upper-midrange and lower treble, while having a slightly dark treble range.”
Audio Discourse (Antdroid)
Genuinely contested. One reviewer calls the MAY 'technically stellar' with 'excellent' detail retrieval, resolving more like a pricier set; several others land on middling — clear and clean but average for a good sub-$100 IEM, not a resolution standout — and the harshest critic hears very little resolution at all. Much of it tracks the tuning: the safe treble reads as relaxed rather than incisive, and the set is meant to be EQ'd, so perceived detail shifts with the preset.
Measured
No lab metric settles this — it's a resolution-perception split. Prime Audio lists 'Middling technical performance' as a con; Audio Discourse calls resolution 'generally average, but more than adequate and above grade for this price point'; community reviewers put it 'on par with other good sub 100 USD IEMs' and note technicalities scale heavily with EQ.
Where it splits
Resolves well for the price — technically strong.40%
“The detail retrieval is excellent.”
Bedrock Reviews (Alec)
Middling technicalities — average resolution for the class.60%
“the MAY is clear sounding but lacks a bit of detail”

Two-sided. The small resin shell with its mirrored metal faceplate feels premium and looks the part, and the DSP cable is a near-universal highlight — attractive, light, with a mic and inline controls. But durability and QC are the recurring worry: the mirror faceplate scratches, owners report DSP-cable hiss on some sources, and one reviewer's cable died within weeks (plus scattered channel-imbalance reports) — feeding Moondrop's mixed QC reputation. The companion app is widely called clunky.
Measured
The cable is essentially Moondrop's FreeDSP (a $30 accessory) with MAY-specific presets: a USB-C DAC good to 32-bit/384 kHz with a 9-band on-cable PEQ. Community sources are consistent on the downsides — DSP-cable hiss/crackle on some phones and PCs, a scratch-prone mirror faceplate, and Moondrop's sketchy QC reputation, 'specially in durability' — while praising that a failed cable is cheap to replace and the IEM still works on any 2-pin cable.
Where it splits
Premium-feeling shell and a genuinely nice, versatile DSP cable — a complete package.45%
“The whole package is very complete and I really like how everything flows together”
Audio Discourse (Antdroid)
Moondrop QC/durability is a gamble — dead cables, hiss, a scratch-prone faceplate.55%
“my first cable died without a clear reason within a few weeks of use.”
Bedrock Reviews (Alec)
Contested. Editorial reviewers treat it as an easy $65 buy — effectively two products in one, an IEM plus a reusable DSP DAC cable — that punches above its price. The community is cooler: in a crowded sub-$100 field (Truthear Hexa, Simgot EA500 LM/EW300, KEFINE Klean, ZERO:RED) the MAY is a harder sell, and its DSP-only design with no 3.5 mm option plus Moondrop's QC narrow who it's for. The single loudest critic argues the stock sound doesn't justify it at all.
Measured
Street price ~$65 (Amazon ~$59, Linsoul ~$74; MSRP $64.99). RedditRecs aggregates 82% positive across 34 Reddit reviews (#71 in its IEM ranking), top con 'Default sound profile not ideal for all' — the recurring community critique is competition plus the DSP-only, no-jack design, not that it's bad for the money.
Where it splits
Two-products-in-one bargain at ~$65 — the IEM plus a reusable DSP DAC cable.60%
“you’re getting two products for the price of one, which makes it pretty good value.”
Prime Audio
A tough sell next to the sub-$100 field — several would point you elsewhere.40%
“Save your money and buy the cheaper IEM.”
Sixaxisorcist, r/iems
Broad agreement on the recipe: a safe, balanced Moondrop house tuning — a sub-bass-focused near-neutral close to the brand's VDSF/Harman-flavoured target, with no shout or harshness. It's an easy all-rounder that doesn't spotlight any one region; the on-cable presets (Standard, Harman and bass variants) let you shift the balance, though the trade-off by design is 'safe' over exciting.
“The bass levels are slightly above neutral with a a focus on sub-bass, with linear mids, and a focus on the upper-midrange and lower treble, while having a slightly dark treble range.”
Audio Discourse (Antdroid)
“The overall IEM tonality is very smooth and enjoyable.”
Audio Discourse (Antdroid)
Measured
ASR's 711 measurement: driven passively the response is within ~2 dB of Amir's target to 6 kHz, and with the Standard preset within ~3 dB to 12 kHz — 'pretty well tuned.' A gotcha: a flat tuning ships loaded on the DAC out of the box, not the advertised Standard, so it's worth setting the preset in the app.
Generally a strength — clean and natural, neither recessed nor shouty, with female-vocal timbre a recurring highlight and no planar 'sharpening.' The one nuance is male vocals: Headfonics finds them a touch light on weight, while Bedrock hears them 'highly intelligible' and surprisingly solid — a minor split within an otherwise well-liked midrange.
“The midrange of the MAY is clean while having a natural timbre.”
Headfonics (Kurt)
“Male vocals are highly intelligible with grit and definition.”

Soundstage
Moderate · 6 srcMiddle of the road, with a mild split. Most reviewers call the stage average-to-slightly-above for the price and a touch intimate/in-head, with better depth than width; one hears it as slightly wider than average. Not a weakness, not a class leader — a competent, rounded space rather than a holographic one.
“The soundstage is a bit small, with a more intimate sound to it, but I did not have any issues with different instruments smattering together.”
Audio Discourse (Antdroid)
“The imaging is very good, with a slightly wider soundstage than average.”
Bedrock Reviews (Alec)
Rated good for the price — placement and separation are accurate and, for some, punch above the class, helped by the two-way hybrid layering. Positioned as competent-to-strong rather than pinpoint, and better than the benchmark Truthear Hexa to at least one listener.
“The instrument separation is slightly better than expected for the price point, more like a $100 IEM than a $65 IEM.”
Bedrock Reviews (Alec)
“May feels more spacious while Hexa is more closed in. Imaging and layering on May is better.”

Not a highlight, and reviewers don't fully agree. Bass slam is called punchy and satisfying, but macro-dynamics draw the weakest marks — one reviewer hears loudness shifting between bass, mids and treble, another rates overall dynamics as merely mid-tier (as many sub-$100 sets are). Fine for casual listening, short of effortless.
“For dynamics, it’s unfortunately done poorly.”
Headfonics (Kurt)
“Generally, the dynamics are very mid-tier, but few IEMs in this price range have great dynamic range.”
Audio Discourse (Antdroid)
Comfort
Strong consensus · 7 srcA near-unanimous strength — a small, light, low-profile shell that many call one of the comfiest IEMs they've worn, secure enough to wear for hours or even to sleep. The only caveat is the box: just basic generic tips, so tip-rolling is recommended for the best seal.
“As someone who can fit nearly all IEMs, even the bulky Sony IER-Z1R, this MOONDROP MAY is one of the comfiest IEMs I’ve worn.”
Headfonics (Kurt)
“I found the Moondrop May extremely comfortable as well as the most securely fitting Moondrop IEM I’ve used”
Bedrock Reviews (Alec)
Isolation
Moderate · 3 srcGood for a vented dynamic-hybrid IEM — the deep, secure fit blocks a fair amount of outside noise with little leakage, better than average for the class. Little disagreement here.
“The isolation of the MOONDROP MAY is good. Due to how deep it goes in the ear, there is no noise leakage during use.”
Headfonics (Kurt)
“May is exceptionally comfortable (for my ears) while offering excellent passive noise isolation.”
