Binary Dynaquattro VS Open Audio Siren

Youtube Video Summary

Binary Dynaquattro comes dressed to impress: a larger, comfy shell that sits better than it looks, though seating can be a touch finicky. Accessories feel thoughtfully chosen—a Pelican-style case, usable tips, and a standout cable with a screw-lock modular plug (ships with 4.4 mm) and a handsome gunmetal vibe; the chin slider actually works and handling is supple with a slight rubbery grip. Build notes versus peers: it’s notably bigger than Gizaudio Chopin (flat 2-pin vs. Chopin’s recessed) and a bit larger than AFUL Magic One, but overall comfort remains solid.

The tuning aims dead at a preferred target: rich, deep sub-bass with restrained mid-bass for a clean foundation, energetic mids, and a deliberate 4–6 kHz dip to keep fatigue low; air is “good for the price,” with upper-treble sparkle the only wish-list item. Technicals read 9.5/10 bass, 9.5/10 mids, highs a notch behind, plus nice imaging, pleasing note weight, and a natural stage/resolution balance. Versus the field: deeper, higher-quality bass than Chopin; competes surprisingly well with the pricier Thieaudio Oracle MK3; more engaging than the neutral-leaning Moondrop x Crinacle Dusk; preferred over Project M thanks to truer target adherence; trades blows with Dunu Da Vinci (Da Vinci = a touch more upper air; Dynaquattro = better bass/mids). Close kinship with Juzear 61T (choose Dynaquattro for richer bass, 61T for a more inoffensive, cheaper take), and consider Letshuoer Cadenza 4 if similar mids with less bass is the brief.

In practice this is a fun, fatigue-lite, bass-quality-first all-rounder with tuning doing the heavy lifting—“tuning trumps technicality” in the best way. The package, from the utilitarian accessories to the modular cable, matches the sonic story: high value, target-true, and easy to recommend for music and gaming (9/10). Call it a five-star pick and a “100-point overall” vibe for listeners who want clean sub-bass authority, lively mids, and a relaxed upper-mid/low-treble that invites longer sessions without dulling the experience.
