By aspect — in detail
Broad agreement on the recipe: a warm-neutral, mildly U-shaped tuning built around the 'meta' reference, with a touch more excitement in the bass and treble than a strict reference set — versatile and inoffensive across genres, a 'safe buy.' The trade-off, by design, is that a bit of extra upper-frequency energy is what a minority later hear as hot; its own tamer successor, the Odyssey 2, sands that down.
“ZiiGaat Odyssey is a competent set of 3-way hybrid IEMs with a slightly u-shaped tuning.”
RudeWolf, r/headphones
“It's rooted on the new meta with adding a bit more excitement in the bass and treble, but really just a bit.”
Endoky, r/iems
Measured
Crinacle's Hangout.Audio 5128 database lists the Odyssey (✅ approved, ~$230) measured against the JM-1 / PopAvg-DF 'meta' target; ZiiGaat's own spec sheet quotes 20 Hz–23 kHz, 18 Ω, 104 dB and 0.05% THD. IEMRanking's 14-review aggregate reads it as a warm-leaning neutral with a tasteful bass boost and a midrange-led 'Meta' balance that 'can sound calm at low volume but becomes wider and more immersive when pushed.'
Liked for quality more than quantity — a tight, controlled, sub-bass-leaning low end with 'subwoofer-like' quick decay that stays clean and out of the mids. It is explicitly not a basshead set: sub-bass rumbles when asked, but mid-bass punch is the softer point, and the whole region scales with volume — thin or 'uneventful' at low levels, punchy when pushed. A basshead minority find it short on slam.
“bass is tight, controlled, and hits the sweet spot for people like myself who enjoys the rhythmic thump of bass without it overpowering the rest of the song.”

“There's ample bass but not for basshead. It's sub base has rumble but the midbass is less impactful / presence.”
Jason Ng, ziigaat.com (owner)
Measured
A single custom 10 mm 'Topology' dynamic driver; ZiiGaat describes the bass as 'subwoofer-like performance, with powerful and impactful hits that quickly decay.' Headfonics hears the deepest sub-bass roll off early ('some of that deep presence feels missing'); the critical camp hears the other extreme when they crank it — Ferox_Dea calls it 'sharp with no thumb,' and a self-described basshead in the 'dissatisfied' thread finds it 'lacking punch … unless you turn the volume up.'
Mids
Strong consensus · 7 srcThe consensus highlight. Despite using balanced armatures, the midrange is repeatedly called natural and clean with little BA timbre, vocals full and slightly forward, and — notably — no shout even when the upper mids lift. The lone caveat is a minority who need a moment to adjust to the timbre.
“There’s very little of that typical BA timbre, leaving instruments and vocals sounding natural and realistic.”
Headfonics (Kurt)
“There’s no shoutiness or harshness, even when the upper midrange starts to peak, making longer listening sessions quite easy on the ears.”
Headfonics (Kurt)
“separation was much better, with vocal detail being the thing that really had me with that “wow” factor.”

The main fault line — and it splits two ways at once. Most reviewers hear the top end as smooth, controlled and non-fatiguing, rolled off in the uppermost octave; detail-seekers read that same roll-off as short on air and sparkle. But a treble-sensitive minority hear the ~5 kHz lower-treble lift as sharp or sibilant, and because the set scales with volume, that edge shows up most when you turn it up. How it lands depends heavily on your ears, tips and listening level.
Measured
The Hangout.Audio 5128 measurement shows the 'meta' shape — a pinna rise through the mids, a lift around 5 kHz and a rolled-off top octave. IEMRanking's 14-review aggregate names the split outright: the '#1 repeated complaint' is 'lower-treble heat (~5 kHz) and/or "safe" upper treble that can limit sparkle/air,' and it flags that 'treble-sensitive reviewers tend to rate it lower.'
⚠ vs. listeners — One tuning, opposite complaints. The mild ~5 kHz lift plus a rolled-off top octave reads as 'refined and non-fatiguing' to most, as 'dark / no air' to detail-chasers, and as 'too bright / sharp' to the treble-sensitive when they push the volume — a ziigaat.com owner pins it as 'a little bit of zing in the high-mid to treble transition, but only with bright vocals and at higher volume.' Tips, impedance adapters and listening level move it more than any single 'true' treble does.
Where it splits
Smooth, safe and non-fatiguing — rolled off up top, easy for long sessions (some wish it had more air and sparkle).62%
“The ZiiGaat Odyssey’s treble has a smooth and relaxed character, leaning slightly towards a darker tone.”
Headfonics (Kurt)
The ~5 kHz lift turns sharp / sibilant, especially at higher volume.38%
“Bass was sharp with no thumb, it was so bright I couldn't listen to it over 30% volume when explorer passed 70 with ez.”

Soundstage
Contested · 6 srcGenuinely split. Several reviewers hear it as wide and immersive for an IEM — a strength for the price — while one editorial voice hears it as small and in-your-head. The reconciler that recurs is volume: multiple owners say the stage only opens up once you push the level, which fits the set's overall 'scales when driven' character.
Measured
IEMRanking's aggregate calls the stage 'often described as wide and more immersive at higher volume; depth/height are solid but not "giant holographic"' — the volume dependence both camps circle around.
Where it splits
Wide and immersive for an IEM.66%
“I was very pleasantly surprised with the soundstage and imaging as it’s rather wide and articulate without making things sound too distant.”
RudeWolf, r/headphones
Small and in-your-head.34%
“Soundstage is relatively small and cramped.”
Headfonics (Kurt)
A clear strength for the bracket, with less disagreement than the stage width. Instruments and vocals place accurately, and separation holds up even in busy tracks — a repeated point of praise.
“Imaging is surprisingly accurate, with vocals and instruments placed clearly in the mix.”
Headfonics (Kurt)
“Separation is handled well, even during complex or busy tracks.”
Headfonics (Kurt)
Measured
IEMRanking's aggregate rates imaging 'a clear strength for the bracket: precise placement and good positional reads,' and layering/separation 'above average for ~$200–$250 … but not class-leading versus the top technical sets.'
Good for the price but not a resolution leader — the honest ceiling of an otherwise strong set. There is enough detail to enjoy well-recorded tracks, and much of the clarity is 'real' (from clean tuning and separation), but the presentation isn't hyped, dense mixes can blur, and it trails the class technical kings.
“There’s enough resolution to appreciate detailed recordings, but the decent tuning means that you have to listen in for it, as it’s not particularly hyped.”
RudeWolf, r/headphones
“Detail retrieval isn’t the treble’s strongest point, with certain elements in tracks sounding dampened.”
Headfonics (Kurt)
Measured
IEMRanking's aggregate frames it as 'mostly real detail from clean tuning and separation, though some perceived clarity can come from the 5 kHz energy,' and notes 'dense mixes can blur compared to more resolving competitors.' A beginner owner echoes the ceiling — busy shoegaze 'felt thin and metallic.'
Punchy and dynamic when it has power behind it, with strong mid-bass drive — but slam and texture aren't top-tier, and the recurring caveat is scaling: from a weak source or at low volume it can sound flat and unremarkable, then comes alive when you push it.
“The dynamics are consistent, with the midrange staying prominent while the bass and treble take on more supporting roles.”
Headfonics (Kurt)
“The bass is punchy, and the soundstage is wide, clear, and well-pronounced. To really enjoy it though, I find I need to push the volume up a bit—that’s when the presentation feels immersive.”
FrostyAd6068, r/iems
Measured
Easy to drive on paper (18 Ω, 104 dB) and IEMRanking reads it as 'more punchy and dynamic than flat/sterile'; but it can be source-sensitive — Endoky notes 'a noticeable background hiss and noise floor' from poor sources — and both community and critical listeners agree it wants a little volume to wake up.
Split by ear. The lightweight resin shell is comfortable for hours for many — some even sleep in it — but it's a bulky, thick housing, smaller ears struggle, and the stiff stock silicone tips are widely disliked (foam or third-party tips fix both fit and sound). 'Big and chunky' and ear strain complaints recur.
“The ZiiGaat Odyssey delivers great comfort despite its larger shell size.”
Headfonics (Kurt)
“I just feel like they’re so big and chunky while in ear.”
Educational_Egg6971, r/iems
Measured
The stock silicone tips are a common weak point — Headfonics found them 'a jab in my ear,' FrostyAd6068 gets 'ear strain after 30–60 mins,' and RudeWolf notes the tips 'wouldn't seal at full insertion depth' until swapped. IEMRanking's aggregate adds that 'small ears may get hotspots or a "too chunky" feel.'
Isolation
Moderate · 2 srcAverage — a decent seal, but a vented shell that lets more outside noise through than a tight-sealing set. Fine for casual listening, not a top isolator; little real disagreement.
“Isolation, on the other hand, is just okay. External sounds still manage to slip through more than expected, especially in noisier environments.”
Headfonics (Kurt)
Measured
IEMRanking's 14-review aggregate lands in the same place: 'Isolation is average-to-good: decent seal, but venting and shell size mean it's not a top isolator.' Headfonics attributes the leakage to a larger-than-average vent near the 2-pin connectors.
Two-sided. The glossy resin shell and sparkly 'nebula' faceplate look good, and the metal nozzle with a retention lip that stops tips slipping off is a genuinely liked touch. The stock cable is the opposite: thin, plain and — unlike the pricier Odyssey 2 — fixed and non-modular, a consistent gripe alongside a spartan kit (case, cable, two tip types). One owner also reports the nozzle filters coming loose over time.
“What I do love is the metal nozzle with a retention lip that prevents eartips from slipping off.”
RudeWolf, r/headphones
“There’s also a noticeable flimsiness to it, making it feel like it could snap with a firm tug.”
Headfonics (Kurt)
Measured
A fixed 1.2 m copper cable with a single termination (no 4.4 mm option), S/M/L silicone + one foam tip set and a pleather case. RudeWolf notes 'the 220EUR Odyssey basically comes with the same set as the 1700EUR Jupiter,' and a ziigaat.com owner (Marc) reports 'ear filters fall out after normal usage' — the shell is liked, the accessories much less so.
Broadly seen as a strong all-rounder for roughly $220–230 — an 'endgame for most' that does everything well and lands close to pricier hybrids for less. The dissent isn't really about price-per-performance: the listeners who returned it did so over treble-sensitivity or fit, not because they thought it was poor value.
“In it's price range, I would easily give the Odyssey a 10/10 Score with the Label "Endgame for most".”
Endoky, r/iems
“the Tea Pro is very similar it just has more drivers, but overall the Odyssey is 90% the way there for $100+ less.”
gobolin-deez-nuts, r/iems
Measured
Street price roughly $220–230 ($229 at Headfonics / Bloom Audio, $230 on the Hangout graph). IEMRanking aggregates 14 expert reviews to 7.6/10 (A Tier) and notes it's 'often framed as stronger value than at full MSRP' at typical street discounts; RudeWolf grades it a 'Strong B+' with 'very few qualms about recommending it to most listeners.'
