7Hz Elua Ultra VS CCA Phoenix

Youtube Video Summary

7Hz Elua Ultra doubles down on fun with a 10 mm + 8 mm dual-dynamic (LCP) design and a smoothed, modified-Harman tilt. The result is a lively V/W flavor: a proper ~10 dB sub-bass shelf that stays tight, forward-enough vocals, and an energetic upper treble that invites turning the volume up. Tuned for pop and EDM, it comes across as a clear, high-engagement banger without burying the mids.

The surprise is control: bass remains tidy rather than boomy, the mid-bass dip creates space so the mids sound open and resolved, and the presentation expands into a stadium-style stage with vivid imaging. Treble transitions smoothly from lower to upper into air, giving synths real soar; compared with EDC Pro, Elua Ultra feels bigger and technically cleaner at the price.

While the emphasis is on fun over natural timbre and the upper treble can run bright for sensitive ears, the overall package performs strongly for its bracket: turn it up, enjoy the energy, and sample dual-DD excitement for very little money.

CCA Phoenix marks a fresh start under ND Audio with a polished metal shell, normal 2-pin socket, improved accessories, and a budget LCP single dynamic driver. On the graph it rides above the Harman target from the upper mids through treble, which reads bright at higher volume; low-volume listening is more agreeable. The driver quality is the story: fast, controlled, and unusually clean for the price, and with a touch of EQ it shows notably better clarity and composure.

Bass is a tilted profile with less sub-bass and a modest mid-bass lift, giving a tight, bouncy punch that suits pop, EDM, and hip-hop. The leaner shelf reveals the mids with good separation and minimal bloom, while the treble extends strongly but is too energetic in the 3–7 k region, flattening stage at louder levels. Trim the 3–20 k region by about 2 dB and staging gains dimension and imaging snaps into place. As a sub-30 USD set for tinkerers, Phoenix is a standout driver held back by hot tuning out of the box.

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.
