Compact 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 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.
