Moondrop RAYS

A $65 Moondrop MAY in gamer colours with a smarter cable — and whether that is a bargain or a mark-up is the whole argument.

Moondrop RAYS

The short version

What to know.

A USB-C DSP hybrid tuned, by default, to a restrained, neutral-leaning profile: about 5 dB less sub-bass than Harman, a gentle upper-midrange and a top end that rolls off above 9 kHz. Sources agree on a natural midrange, an accurate left-right image with little depth, and an unusually comfortable, flush-fitting shell; they rate detail as merely adequate. They split on whether the treble is smooth or dull, on whether the sound is punchy or soft through the DSP cable, and — most of all — on value, because the earpieces measure the same as the $65 MAY and the $35 difference buys the cable, the mic, the game presets and the web app. Its Amazon aggregate is the lowest of any Moondrop covered here: 3.8 stars with 17 % one-star reviews, almost all about cables, dead channels or devices that stop recognising it.

About this product

The April 2025 original — the first and, as of September 2026, only product in Moondrop's "Gravity" pro-gaming series: one 10 mm sapphire-plated dynamic driver plus one 6 mm annular planar per side, a translucent dark-green resin shell with an iridescent violet faceplate, and a 0.78 mm 2-pin socket. It ships only with its USB-C DSP cable (sound card, on-chip parametric EQ, inline mic with hardware noise-cancelling); there is no 3.5 mm version. Not the Moondrop MAY (2024) — although measurements say the two share the same drivers and shell, the MAY costs about $65 and its DSP default is tuned differently — and not the Chu II or Aria 2 DSP variants.

The Moondrop RAYS is what happened when the most-recommended budget IEM maker on the internet decided to sell to gamers: a hybrid dynamic-plus-planar earphone in a translucent green shell with a violet, oil-slick faceplate, sold at $99.99 only with a USB-C cable that carries a DAC, a noise-cancelling mic and a DSP that stores your EQ. Plug it into a PC, a phone or a PS5 and the tuning you set in Moondrop's web app comes with it, along with one-click presets for Valorant, Apex, CS2 and a couple of dozen other titles.

Within days of launch, graph-readers noticed that the earpieces measure identically to Moondrop's own MAY, which costs a third less. That fact never went away, and it split the reviews cleanly: for one camp the RAYS is the first gaming IEM that actually solves the "best IEM for gaming" question; for the other it is a repaint with a $35 software surcharge. Owners, meanwhile, argue about something neither camp of reviewers saw — whether the cable lasts.

A good fit for

  • Competitive players who want a mic, DAC and per-game EQ in one plug-and-play USB-C cable
  • Console and multi-device users who want one stored tuning to follow them from PC to PS5 to phone
  • Long sessions — the shell is the comfort benchmark at this price
  • Listeners who prefer a relaxed, non-fatiguing top end over sparkle

Think twice if

  • You already own a MAY — the earpieces are the same, and its DSP cable and app already exist
  • You want sub-bass rumble or treble air out of the box (both sit well under Harman by default)
  • You need a 3.5 mm jack, an Xbox controller connection or an amp — it is USB-C only
  • You want the longest-lived cable at the price: the failure reports cluster on the DSP cable
  • You mostly listen to music — most reviewers find a $65 MAY or a $50 single-DD equally good for that

1 Strong agreement6 Mostly agree5 Divided opinions

Common ground7

  • One of the most comfortable shells at the price — small, flush, stable for hours
  • A natural, centred midrange with more body than the MAY's default and no shout
  • Accurate left-to-right imaging that makes footsteps and reloads easy to place

Points of contention6

  • Treble: smooth and fatigue-free, or rolled-off and dull — the same measured roll-off read two ways
  • Value: an all-in-one gaming kit worth $100, or a $65 MAY plus a $35 software surcharge
  • Build: reviewers found it well made; owners report dead channels, failed cables and devices that stop recognising it

Band: opinion spread · Dot: weighted average

Most sources describe the default bass as restrained, tight and clean — enough weight for explosions, no bloat over footsteps — and several call that ideal for competitive play. A smaller group wants more: Jays Audio and IEMRanking's user reviewer call the sub-bass weak, and Paul Wasabii hears the dynamic driver as slightly loose, masking the planar when bass is raised. One Japanese owner-reviewer found the opposite for Apex — enough low end to blur footsteps until he cut it in the app. The presets move this a long way in either direction.

“The MOONDROP RAYS delivers a bass response that leans more neutral than boosted. It avoids being overly punchy but still gives the mix enough body to prevent it from sounding flat.”

Kurt, Headfonics

“The 10mm sapphire-plated dynamic driver delivers controlled bass, emphasizing midbass punch over deep subbass extension.”

Gökhan Aydin, MOONSTAR Reviews

“The 10 mm sapphire-plated DD sounds a bit loose; too much bass quickly masks the 6 mm planar, dulling clarity, stage and positional cues, so less bass works better.”

IEMRanking (summarising Paul Wasabii)

“They are stronger in bass, meaning better explosions and gun shot sounds.”

Lorengrin, r/iems (via RedditRecs)

Measured

Seven rigs agree within 1.8 dB: the DSP default sits at about +4 dB from 20 to 50 Hz (normalised to 500 Hz), roughly 5 dB under the Harman IE 2019 shelf, with the lift already gone by 200 Hz. On an analogue cable the same earpieces measure +11 dB at 30 Hz — the May's shelf — so the restraint is a DSP choice, not a driver limit. The FPS presets trim sub-bass by 2–4 dB and add 4–5 dB around 200–300 Hz; the CS2 preset cuts 20–50 Hz by 8–11 dB; the Valorant preset adds 6–8 dB of bass instead.

What to keep in mind 6

  1. A read of where the reviews land as of September 2026, about seventeen months after launch. Most of the detailed write-ups date from the first three months, when the DSP-and-presets idea was new; the later owner reports are the ones that speak to how the cable holds up.

  2. Amazon's 3.8 stars come from people who chose to buy it, so even that figure skews positive — but it is also where the reliability complaints live, so read the one-star share alongside the average.
