7Hz Elua Ultra reviewed by Jaytiss
2025-08-19Compact and comfortable, the 7Hz Elua Ultra brings a tidy dual dynamic driver package for around $30. The rounded shell uses a pretty metal faceplate, sits light in the ear, and isolates better than the 7Hz Zero/Zero 2. Details: flat 2-pin connectors, proper venting, two colorways, and a nozzle that grips tips well. The stock cable is fine for the price—right-angled 3.5 mm, 7Hz branding—but the Y-split wanders and there are no clear L/R markers. A handful of colorful tips is included; nothing fancy, but serviceable.
Sonically, this is a bassy, engaging tune with glidey, impactful low end, upper mids that are present without shout, and treble that’s acceptable yet a bit grainy with limited air and microdetail. The midrange can read a touch lean depending on normalization, giving a mild V/U flavor; still, the overall tonality feels fun and easy to enjoy. Compared against peers, it’s cleaner and less hissy than very V-shaped sets like the G1, shows more bass and upper mids than 7Hz Zero 2, yet can’t match higher-tier options (e.g., Punch Audio Martillo) for technical performance. Verdict: a solid B—good value and a worthwhile pick for listeners wanting a budget bass emphasis, even if the “twinkle” and ultimate resolution are a step behind pricier favorites.

The Tanchjim Bunny offers a balanced, warm sound signature that works well across genres. Its bass is full and extends decently, though texture lacks refinement, while the midrange presents vocals naturally with good clarity and minimal harshness. Treble remains smooth and inoffensive, contributing to a non-fatiguing listen, but the soundstage is average in size and separation struggles with complex tracks.
A major highlight is the optional DSP cable, which unlocks extensive customization via Tanchjim's app . This allows access to EQ presets, a 5-band parametric equalizer, and a community-driven profile library, significantly enhancing flexibility . While the Android app experience is robust, iOS functionality is reportedly less reliable . For its price, the Bunny delivers commendable technical performance and exceptional value, especially with the DSP version.

The 7Hz Elua Ultra delivers a powerful and well-defined bass that extends deep without overwhelming the mids, making it stand out in its price range. Vocals are clear and detailed, with a natural presentation that works especially well for female voices, and there's minimal bass bleed into the midrange . The IEM requires a lengthy burn-in period for the drivers to fully stabilize and achieve coherence between the bass and treble.
Treble performance is detailed and expansive, offering good airiness without causing fatigue, though it can lean slightly analytical rather than musical. The accessories are quite basic, including a standard OCC copper cable and a few ear tips, which feels lacking even at this price point . Despite its low impedance, the Elua Ultra benefits from better amplification to overcome its lower sensitivity and unlock its full potential.
Overall, the Elua Ultra punches above its weight with a balanced and speaker-like sound that competes with more expensive models. Its ergonomic, lightweight design ensures comfort for long sessions, but the minimalist unboxing experience is a notable drawback . This IEM is a strong choice for those seeking a fun yet technically competent listen without breaking the bank.

Tanchjim Bunny reviewed by Z-Reviews
Tanchjim Bunny lands as a tiny, cute, ultra-cheap $20 brawler that punches way up. It’s a single dynamic with a clever acoustic maze back-chamber that keeps reflections in check, yielding surprisingly holographic space for something this small. The tuning sits neutral-leaning and intimate—vocals and guitars feel close, detailed, and clean, without the “in-your-face hurts” problem. Bass isn’t a bloated “basshead bomb,” but when fed heavy tracks it digs deep and stays composed; on normal music it behaves, staying tight and controlled.
Build and kit are simple but right where they need to be: detachable 2-pin cable, in-line mic, basic tips (swap to Render-style tips for best seal). There are two versions in the wild—this regular 3.5 mm set and a DSP cable version—yet even straight analog on a neutral source the Bunny sounds shockingly grown-up. Net take: this is a 5:1 value play that can hang with many $100 IEMs, delivering clarity, intimacy, and satisfying low-end control at a price that feels unreal. If the goal is “cheap that actually slaps,” Bunny ears up.
