By aspect — in detail
Mids
Strong consensus6 srcThe headline strength and the one near-universal point of agreement — natural, neutral, tactile vocals and instruments. The only caveats are a minority who find the mids a touch relaxed/unemphasized or occasionally 'wispy.'
“I cannot think of a midrange that is better tuned in isolation.”
Listener, Headphones.com
“The mids on the Meta are special.”
McCullough Audio
“For my personal taste, the mids is on the relaxed side but it is not thin at all”

Linear, neutral mids are the explicit design goal (the tilted diffuse-field target); Listener calls the 200 Hz–4 kHz region 'probably the best IEM I've ever heard.'
Everyone agrees on the recipe — a tilted diffuse-field 'meta' tuning with a bass boost and a treble lift. They split on what that adds up to: a tasteful, mid-centric neutral, or a V-shape (some also find it 'too correct' and short on character).
Measured
Crinacle built it to his IEF Preference 2025 target (a tilted diffuse-field adjustment of JM-1) plus a sub-bass shelf; one owner sums the graph as 'slight emphasis in both the bass and the treble.'
⚠ vs. listeners — Same FR, opposite labels: 'tasteful neutral' vs 'V-shape' is one tuning judged against taste — and a separate camp finds it accurate but 'too correct,' lacking the character of a Volume S or Mega5EST.
Where it splits
Tasteful neutral 'meta' tuning with a bass boost — balanced and musical.57%
“It's the perfect balance of the somewhat boring Meta-style and a fun signature.”
McCullough Audio
Tips into a V-shape — excess bass and treble overshadow the neutral middle.43%
“the boosts elsewhere in the frequency response take what would otherwise be neutral and turn it into a V-shape”
Listener, Headphones.com
Quantity isn't really in dispute — it's a generous, sub-bass-led low end with strong extension and little mid-bass bleed. Quality is the fault line: clean, physical and best-in-class for a 'meta' set to some; lifeless, bloated or short on texture and slam to others.
Measured
Crinacle's B&K 5128 graph tracks his 'meta' target with an added sub-bass shelf; Listener notes the shelf sits lower in frequency than usual, which exaggerates the gap between sub- and upper-bass. The Head-Fi showcase reviewer scored bass 2/5 ('lifeless, lacking texture, dynamics, impact, attack, and tactility'); others call the same low end clean and well-defined.
Where it splits
Clean, physical, among the best 'new-meta' bass.45%
“The bass is very, very good overall. The only IEM that I've heard that beats the Meta in terms of overall bass quality is the Dusk, but that has two bass drivers and costs $150 more.”
McCullough Audio
Too much / lacks quality — bloomy and incoherent, or lifeless and short on slam.55%
“There's just too much sub-bass and mid-bass bloom for the rest of the tuning here”
Listener, Headphones.com
The other big argument, and the most fit-dependent. One camp hears a tasteful, smooth-but-sparkly extension; another localises a sibilant peak around 6 kHz (and again ~8–10 kHz) that turns shouty or fatiguing. Deeper insertion, wide-bore tips, a touch more volume, or a small EQ notch tame it for many.
Measured
oratory1990 (B&K 5128) found it 'lacking a dB or two at 5 kHz and up' relative to target; against that, listeners localise a sharp peak near 6 kHz and again ~8–10 kHz (one owner EQ'd out ~15 kHz; a shared PEQ notches 6.8 and 9 kHz).
⚠ vs. listeners — The graph (and oratory) read the treble as on-target-to-slightly-tame, yet many hear it pierce — a classic ear-canal/tip resonance story. As oratory notes, this exact region varies with individual canal shape, so smooth-vs-sibilant is largely an ears-and-tips outcome, not a single 'true' answer.
Where it splits· split roughly even
Tasteful sparkle — smooth, extended, non-sibilant.
“The treble is emphasized a little bit, while still maintaining extension and natural timbre.”
McCullough Audio
Peaky / sibilant — a chirpy upper-treble or ~6 kHz peak that's shouty and fatiguing.
“an unnecessary upper treble boost committing a chirpy sizzle to basically anything with any energy above 10 kHz”
Listener, Headphones.com
Genuinely split by definition: praised as resolving and transparent by some, dismissed as 'nothing special' by others who hear the apparent detail as treble-driven rather than true resolution.
“They have amazing resolution while somehow being smooth and easy to listen to.”
McCullough Audio
“the Project META doesn't really do anything special for me”
Listener, Headphones.com
Leans modest. The critical read is that slam and macro-dynamics are limited, much like other 'new-meta' sets; a minority finds it plenty engaging and dynamic.
“I would say Project META is roughly as poor as the other “New Meta” sets are.”
Listener, Headphones.com
“it's still very engaging and dynamic.”
McCullough Audio
Mostly positive — a well-balanced, non-claustrophobic stage with good front-back depth and a sense of spaciousness, though it isn't holographic and at least one listener didn't hear the space at all.
“Project META has an exceptionally well-balanced and non-claustrophobic stage and imaging presentation.”
Listener, Headphones.com
“Meta did not sound intimate nor spacious to my ears.”
Head-Fi showcase review
A consistent strength — precise placement and clean separation, with several listeners singling out sharp, even '360' imaging.
“It was quite literally able to accomplish a 360 imaging without any issues for me.”
Head-Fi showcase review
“the placement on the left-right axis is plenty precise and bereft either gaps or any blurring”

Comfort
Strong consensus5 srcBroadly excellent — a small, light, well-molded aluminium shell with a reasonable 5.8 mm nozzle that disappears for long sessions. The recurring caveat is tip-and-fit: stock tips can stick out, and a deeper seal (often with wide-bore tips) both improves fit and tames the treble.
“I find it to be a very comfortable IEM due to its shape and weight. I can easily wear it all day and not notice it.”
Head-Fi showcase review
“the comfort of META's shell is good for me, probably one of the better recent IEMs I've tried in that regard”
Listener, Headphones.com
Measured
Compact anodized-aluminium shell, 5.8 mm nozzle, 19 Ω, 102 dB/mW @ 1 kHz, recessed 2-pin (specs).
Build
Strong consensus4 srcA clear plus — a premium full-metal, serialized shell and an unusually well-liked modular cable (swappable 3.5 mm / 4.4 mm, soft, non-microphonic), plus a roomy hard case. Minor nits: a chin slider that won't always stay put, and friction-fit terminations whose longevity is unproven.
“a full-metal shell at this price point is nice to have”
Listener, Headphones.com
“It is personally my reference point in cables, because I like everything about it.”
Head-Fi showcase review
Isolation
Thin evidence1 srcLightly covered — the few who mention it find the sealed metal shell isolates well, but too few reviewers discuss it to call a consensus.
“it fills the inside of my ear nicely. Likely thanks to this the noise isolation is also quite good.”
Josse (Hangout owner)
Genuinely contested even before you account for scarcity. Some call it a clear over-deliver at $249; others say the much cheaper Kiwi Ears KE4 spoils it, amid grumbling about undisclosed drivers and hype-driven, instant sellouts. As a sold-out limited run, it's now secondhand-only.
Measured
$249 USD ($334.99 SGD), 999 serialized units sold Hangout-exclusive and sold out; a representative owner score is 4.64/5 from 64 reviews on CrinEar's own store. Secondhand prices have run well above MSRP.

Punches above its price.52%
“the Project Meta punches well above its asking price and is impressive”

“I'm also not sure its all that great of a value when KE4 exists.”
