Warmer Harman 2019 with less shouty vocals. Bassy all-rounder with decent tech. Build and plate design is very pretty... but price is a bit high and not that competitive - wait for sale unless you really dig the look.

"Meta" inspired tuning, basically a slightly more detailed Astral with smoother treble and less sub-bass. Less aggressive/in your face vs Astrals. Great details and tech for the price, bright-leaning.
Youtube Video Summary

Ziigaat’s Horizon follows the current meta-inspired recipe—think Astral, Metas, Crescent—but pushes the focus upward: the treble is the most prominent piece here. It’s bright-leaning without turning harsh, giving a crisp, “OCD-like” sense of transient bite and pinpoint imaging. Low end and vocals sit a touch behind the highs, so the presentation feels clean and lively rather than thick; at mid-volume, the top end drizzles detail over the mix like raindrops—engaging and textured, not shouty.

On the technical side, Horizon pulls strong detail retrieval and resolution for the price—above sets like Supermix 4 and near EM10/Volare —yet it doesn’t scale massively because of that treble lift. The bass is snappy and controlled, with good separation, but lacks the slam and rumble seekers of impact will want. Pairing and playlist matter: avoid hot, highly produced pop/K-pop/J-pop or most hip-hop where the combo of elevated highs and lighter bass can feel edgy; it shines with slower pop, R&B, indie acoustics, ballads, and classical where the sparkle reads as “high-fidelity.” Warmer sources help a bit, and tip-rolling (stock black/clear, or bass-adding options like Final E/divinus) can balance things—just skip anything that pushes treble further.

Against close competitors, Astral hit harder down low and feel more V-shaped and contrasty; Crescent is warmer and smoother but not as clear or micro-detailed. Horizon is the cleanest and brightest of the trio, with the most refined treble focus and “tickly” transients. Verdict: a value-minded all-rounder for detail lovers who prefer clarity and air over bass authority—technical, tidy, and energetic at sensible volumes, provided the library isn’t a treble minefield.

The Heartfield CU8 delivers a neutral sound that closely follows the Harman target curve, providing a balanced and accurate listening experience suitable for both critical monitoring and musical enjoyment. Its bass response is tight and textured, with a slight mid-bass bump that adds a touch of warmth without bleeding into the mids, while the treble remains smooth and free of sibilance.

Build quality is a standout, featuring a hand-finished brass chamber that feels premium but contributes to a heavier design, which might affect fit for some users during extended wear. The included cable is thin relative to the IEM's weight, though the deep recessed 2-pin connectors ensure a secure connection.

Overall, the CU8 excels with a natural timbre and cohesive presentation, making it a strong choice for those seeking an analytical yet engaging signature across genres, though its weight and sparse accessories are minor drawbacks. The PUR vibration control system effectively enhances dynamics, allowing its four balanced armatures to perform with the impact of more complex driver setups.

Ziigaat Horizon is a tribrid IEM that combines 1DD + 2BA + 2 planar drivers, positioned at an MSRP of $329; this configuration aims to split bass, mids, and treble duties across specialized transducers for coherence and headroom. These fundamentals are confirmed on the brand’s product page and storefront listings.

Subjectively, community impressions describe robust sub-bass from the dynamic driver, clean mids from the BAs, and airy treble from the planar tweeters, with multiple listeners highlighting a notably expansive soundstage. Head-Fi reviews and threads also call out treble extension claims “up to 40 kHz” and above-average staging for the price class.

In tuning terms, the Horizon trends U-shaped: lifted bass and upper-treble energy provide excitement and perceived width, while midrange presence is more neutral than forward—favorable for pop and electronic but less ideal if you prioritize warm, intimate vocals. Reports also note that pairing and tips can influence perceived brightness and staging, so synergy matters if you’re treble-sensitive.

Like the Top Pro but with more controlled bass and more immediate transient attack. Where the Top Pro sometimes could sound blunted and too soft, the Horizon sounds quite a bit more tactile. Treble maybe not as smooth as Top Pro but as a result it also sounds more alive. Ziigaat has been releasing new IEMs every couple weeks it seems so it's very difficult to keep up with them but this one is a gem.

Super* Review 8* * score rescaled + normalized
Arguably the best in this series so far, it delivers a neutral, transparent midrange, a sub-bass tilt, strong imaging, and a surprisingly dense, engaging presentation. Caveats: a gritty upper treble that’s tip/fit-sensitive, only okay comfort, and a mediocre stock cable.
Youtube Video Summary

The Horizon aims for a neutral-natural tonality with a slightly lean lower midrange, delivering standout vocal transparency and crisp separation. Bass is mostly sub-bass focused—felt and supportive rather than boomy—giving notes a pleasing sense of density without smearing the mids. The trade-off is an elevated upper-treble that adds air and detail but can tilt gritty/sandy if the fit or tips aren’t dialed in.

Build and accessories are a mixed bag: a surprisingly nice carrying case and swappable termination, but a fussy cable and a resin shell that fits deep and may need shorter, grippier tips to shine. Once seated well, the Horizon’s imaging and instrument separation pop, making complex mixes feel organized and engaging.

Versus pricier hype pieces with similar FR, the Horizon feels like a “short king” take: not as refined up top as the best of them, yet more weighty and satisfying than some leaner peers. Compared to something like Volume S at a similar price, this set is clearer and more incisive (better separation), while Volume S is fuller and smoother with punchier bass presence. At $330, it’s the most compelling entry in its family so far—addictive for transparency and staging, with the caveat of treble sensitivity and fit quirks.

Youtube Video Summary

Ziigaat Horizon arrives as a striking tri-brid in the ~$300 bracket (1DD + 2BA + 2 planar) with a tuning that brushes close to Kiwi Ears Astral yet comes across a touch thinner and more balanced. The low end focuses on sub-bass rumble that’s tight, clean, and richly tactile, while mids keep timbre accurate and treble stays controlled—never shouty or fatiguing—yielding a fun-yet-almost-reference presentation. Build and comfort impress: ergonomic shells with that aqua-to-silver fade can be worn for 8-hour sessions, and the package includes Ziigaat’s new two-pin cable with interchangeable terminations (3.5/4.4), a roomy faux-leather case, silicone sets plus foams; tip rolling (e.g., ASMR tips) pairs well.

In games, ambient clutter drops away and crucial cues get spotlighted with confident imaging, separation, and convincing verticality. Footsteps in Valorant are clear and positional, though the lightest taps can blur a bit under nearby low-end rumble or heavy gunfire; Apex performance is exceptional, just a hair behind Astral/Mangird Tea Pro when ultimates stack; Call of Duty delivers satisfying impact with disciplined decay, though micro-cues can soften during chaos. Net-net, Horizon is a great all-rounder with clean, technical bass and a natural balance that works across titles. On the WallHack list it gets A– overall (A– in Apex, B+ in CoD, Valorant just shy of top marks), primarily nudged down by occasional masking of the lightest cues during intense mixes.
