Youtube Video Summary

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.

Tanchim One Scorings

Average Tunign Grade

E+

Tuning is chaotic and fatiguing, with clashing frequencies that make long sessions unbearable. Every song demands frequent volume adjustments.

Average Technical Grade

E-

Everything sounds flat and suffocated, with even elementary passages losing definition and energy. Expect little in the way of micro-details.

Mids C-

Midrange is passable yet unrefined, revealing grain and occasional harshness. It sounds a bit grainy on detailed recordings.

Treble E-

Highs sound veiled and distant, draining life from the mix. Hi-hats fade before they start.

Dynamics E-

Dynamic expression is extremely poor, draining impact from every hit. Notes lack the startle or decay they need.

Soundstage D

The presentation sketches a narrow arc while leaving the vertical and frontal layers untouched. Complex mixes blur together quickly.

7Hz Elua Ultra Scorings

Average Tunign Grade

B-

It sounds pleasant overall, with some uneven spots that hint at room for refinement. Vocals remain pleasant despite the imperfections.

Average Technical Grade

C+

An honest, middle-of-the-road performance preserves structure without chasing micro-detail. It's respectable for everyday listening sessions.

Mids B

The mids are articulate and well-balanced, lending body to instruments. Instrument layering remains stable.

Treble C+

Treble feels agreeable overall, bringing sparkle without significant fatigue. You get a polite sense of air.

Dynamics A-

Dynamic performance is excellent, combining sharp transients with strong contrast. Transients snap with authority.

Soundstage B

Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
