By aspect — in detail
Broad agreement on the recipe: a balanced, gently V-shaped, warm-leaning tuning built to the 'meta' / JM-1 reference target — versatile and inoffensive across genres, closer to neutral than to a fun-boosted V. The trade-off, by design, is that it reads as safe rather than exciting; the original Odyssey was bassier and more V-shaped, and this successor is tamer.
“The Odyssey 2 is a gently-V-shaped IEM featuring well-extended, but not dramatic, bass, lukewarm lower-mids, lifted upper-mids, and mildly-lifted treble.”
Resonance Reviews (Aaron)
“I find the Ziigaat Odyssey 2 to have a meta tuning that is quite neutral and balanced, leaning slightly warm”
zipx1, r/IemReviews
Measured
Frieve reads it as Harman-adjacent from multiple databases: sub-bass elevated approximately 6 dB over the mids, “a pinna-compensation rise of approximately 6.3 dB at 3 kHz,” a 3–4 dB lift near 5 kHz, and treble roll-off above 10 kHz — the 'meta' target reviewers cite. HiEnd Portable frames it as “tuned according to the META tuning,” starting slightly higher in the sub-bass than the reference.
Widely liked for quality — a deep, well-extended, tight sub-bass that stays clean and out of the midrange, praised as controlled rather than boomy. Quantity is the softer point: it isn't a basshead set, and a few owners want a touch more mid-bass punch, while a minority find it a little boomy for rock. The recurring practical caveat is power: with a weak source it can sound thin or 'uneventful' down low and needs a little volume or a better amp to come alive.
“The Odyssey 2’s bass is tight, punchy, and well-controlled. It is well-extended and potent, but not dominant.”

“I'm left wanting just a bit more punch from the bass and mid bass”
Drang99999999999, r/IemReviews (owner)
Measured
A single 10 mm 2nd-gen bio-cellulose dynamic driver; Frieve measures the sub-bass lifted about 6 dB over the mids — a modest, sub-bass-leaning shelf, not a basshead boost. JAYYAUDIO flags the scaling: “with less power the Odyssey 2 sounds uneventful in the low-end,” and a Linsoul owner (RomaDVD) hears the other extreme — “The low frequencies are boomy, with a slight bass overload.”
Mids
Strong consensus · 8 srcA consistent highlight — clean, natural and transparent, with vocals a recurring favourite and, notably, no shouty upper-mid glare that plagues cheaper sets. The 'meta' upper-mid rise pushes vocals slightly forward; the one caveat is a mild lower-mid recession that leaves the mids sitting a hair behind the bass and treble.
“The Odyssey 2’s midrange is clean, clear, and extraordinarily transparent.”
Resonance Reviews (Aaron)
“there's no shout, no harshness, just a natural and organic mid range”
higherdotedu, r/inearfidelity
“Mids sit a little behind the lows and highs but remain well-resolved.”
Mobile Audiophile (ADR)
The main fault line. Most reviewers hear the top end as smooth, controlled and non-fatiguing — deliberately rolled off early to avoid sibilance, a plus for treble-sensitive and long-session listeners. A second camp hears the same tuning as too rolled-off: short on air, sparkle and extension, and not the last word in detail. Separately, a minority react to the lower-treble/upper-mid lift as slightly bright or even fatiguing — so how it lands depends heavily on your ears, tips and volume.
Measured
Frieve measures significant treble roll-off above 10 kHz (about 6.5 dB below mid-level by 15 kHz), over a 3–4 dB lift near 5 kHz — which is why most hear 'smooth and safe' and a detail camp hears 'no air.'
⚠ vs. listeners — One tuning, opposite complaints: the early roll-off reads as 'refined and non-fatiguing' to most, as 'dark / lacks air' to detail-seekers, while a few instead flag the 5 kHz region as bright — RedditRecs' aggregated cons even list 'Overly bright treble,' and Mobile Audiophile warns the treble energy 'may be fatiguing for sensitive listeners.' Preference, tips and volume move it more than any single 'true' treble does.

MoonStar Reviews
Soundstage
Moderate · 6 srcRated wide for an IEM and a genuine strength for the price, if not holographic. It leans wider than deep, and the milder dissent is that the mid-forward, dense presentation keeps it somewhat in-the-head rather than expansive — competent staging rather than a class leader.
“produces pretty wide soundstage for an IEM, creating a spacious and three-dimensional listening environment”
MoonStar Reviews
“Soundstage: Decent, mostly in head typical for mid forward tuning, but never claustrophobic”
higherdotedu, r/inearfidelity
Solid and precise for the money — instruments and vocals place accurately, even in busy mixes, helped by the wide stage. Positioned as competent rather than pinpoint or holographic.
“Imaging precision is pretty high for a IEM at this price level”
MoonStar Reviews
“Imaging: Solid for the price, though not super holographic”
higherdotedu, r/inearfidelity
Good for the price but not a resolution leader — the honest ceiling of an otherwise strong set. Micro-detail comes through better than expected, yet several reviewers note the dense, smooth presentation masks the finest cues, and both a measurement site and community reviewers place it behind class rivals for outright technicalities.
“Micro-detail retrieval is better than expected”
Mobile Audiophile (ADR)
“there are other IEMS with better resolution in this price range”
HiEnd Portable
“Slightly less technical versus the Supermix4 and Blessing 3/DUSK”
JAYYAUDIO, r/iems
A quiet strength when it has power behind it — reviewers single out the effortless quiet-to-loud swings and quick, capable drivers. The catch is the same scaling caveat as the bass: from a weak source or at low volume it loses some of that punch.
“Zimmer’s Time swelled from quiet to thunderous with a weight I’d expect from pricier monitors.”
Mobile Audiophile (ADR)
“barely register as a challenge for the Odyssey 2’s quick and performant drivers”
Resonance Reviews (Aaron)
Measured
Easy to drive on paper (20 Ω, 105 dB), but community reviewers stress it wants a little juice: JAYYAUDIO and RedditRecs owners both note it can sound 'dull' or 'uneventful' at low volume and tightens up from a cleaner, more powerful source.
Mostly a plus — a lightweight cast-aluminium shell many wear for hours, and several owners prize its shallow, unobtrusive fit. But it's a medium-to-chunky housing, and fit is where opinions split: a minority find it protrudes or seats poorly, smaller ears feel it more, and the stock tips are a common weak point — RedditRecs' aggregated cons even list 'Uncomfortable and poor fit,' so tips and ear shape matter.
“I managed a three-hour listening stretch without discomfort, and I only noticed them when I stood up to grab a glass of water.”
Mobile Audiophile (ADR)
“I noticed slight protrusion in smaller ears during testing”
MoonStar Reviews
Isolation
Moderate · 4 srcAbove average for a hybrid IEM and a mild bright spot — a deep, occlusive seal that handles commutes and offices well. Little disagreement, and it depends on getting a good seal from the tips.
“I run the Odyssey 2 with its medium stock clear eartips as they isolate pretty well”
Resonance Reviews (Aaron)
“This gives me a complete, very occlusive fit with minimal movement and great isolation.”
HiEnd Portable
Two-sided, but the split is consistent. The cast-aluminium shell with hand-poured resin faceplates is a near-universal highlight — several call it the best ZiiGaat has built. The stock cable is the opposite: a thin, plain-feeling braid that owners routinely single out as the weak link (and swap), and the modular plug is friction-fit with no locking mechanism. Accessories and the case, by contrast, are well liked.
“This is the highest-quality shell ZiiGaat has ever released, and is on-par with IEMs like the Xenns Mangird Tea Pro.”
Resonance Reviews (Aaron)
“I don't like the stock cable, it's too thin and it looks cheap except for the swappable 3.5mm and 4.4mm ends”
Monk_The_Banana_Scug, r/iems
Measured
Cast-aluminium alloy shells with hand-poured resin faceplates; a 4-core OCC + silver-litz modular cable (2-pin 0.78 mm, swappable 3.5 / 4.4 mm). RedditRecs' aggregated cons lead with 'Poor quality stock cable and tips,' and a community owner sums the consensus up as “solid build (minus cable).”
Genuinely contested. Most editorial and community voices treat it as an easy, versatile pick that punches above its ~$249 price — RedditRecs' top pro is 'Exceptional value for money.' The measurement camp argues the opposite: that it's only average measured performance built from off-the-shelf Knowles parts, and that the same 'meta' tuning is available cheaper (the ZiiGaat Daybreak) — so you're paying for the shell and the name, not for measured fidelity.
Measured
Street price roughly $224 (Amazon) to $249 (Linsoul MSRP). RedditRecs aggregates 73% positive across 102 tallied Reddit reviews (74 positive / 20 mixed / 8 negative, #14 in its IEM ranking), with 'Exceptional value for money' its leading pro. The critical camp's cross-shops are the ZiiGaat Daybreak (cheaper, same 'meta' tuning) and Mega5EST (pricier, similar) — the r/iems 'hype train' post puts it plainly: “this is just JM1 meta. If you want this tuning for cheaper, Daybreak is available.” Frieve scores cost-performance 0.1, calling it roughly ten times the cost of a measured-equivalent set.
Where it splits
An easy, versatile all-rounder that punches above its price.72%
“the Odyssey 2 presents a strong value-proposition for seasoned audiophiles and new listeners alike”
